Student Types


  • Students are defined as new students in the academic year during which they are matriculated. After that academic year (2 semesters), they will be called Returning Students.

  • As new students may only start bidding for modules after they are matriculated, it is crucial that they observe the registration time schedule (drawn up by the Registrar's Office). Hence, for Semester 1, new students will start bidding from Round 1C onwards. However, they may place advance bids earlier if they have completed their matriculation. (See instructions for students on Advance, Open and Close Bidding). Once Round 1C is completed, the new students will proceed to Round 2A. New students should read the descriptions of all the rounds.

  • To ensure that new students can secure faculty modules, there will be a separate module quota for new students in their first and/or second semester of studies. This way, they are protected from the returning students who have more bid points than them since they were able to accumulate unused bid points in previous semesters. Regardless of when a student is matriculated, he/she will always enjoy protection for 2 consecutive semesters. E.g. when a student matriculated in 2008/2009 semester 1, he/she will be protected for 2008/2009 semester 1 and 2 and if he/she matriculated in 2008/2009 semester 2, he/she will be protected for 2008/2009 semester 2 and 2009/2010 semester 1.

  • For Semester 2 registration, new students may participate in activities of Round 0 (see description for each bidding round) together with the returning students. They will be protected for a module if there is still a separate quota for new students. If a separate quota is not set aside for new students, the latter cannot bid until the balance of vacancies (left-overs from bidding by returning students) become available. Typically, the balance of vacancies will become available in Round 2A.

    Please refer to activities during each bidding round for more information.


  • Returning students are all other students who are not new or newly transferred.

  • Depending on eligibility/priority for a particular bidding round, a student will get to view only those modules that he/she is permitted to place bids. As such, the student must wait his/her turn at the appropriate bidding round.

  • Students will not be able to log onto CORS when bids are being processed or when maintenance is required. In addition, please note that telephone inquiries will be handled during office hours only. The exact configuration for the duration of each bidding round may change. Users are advised to check the CORS website (http://www.cors.nus.edu.sg) for the latest updates.


Special Term

  • At this stage, students will not be required to bid for modules that are registered for studies during the special term. They register in accordance with the instructions of the Registrar's Office.

Late Matriculation

  • Students will join the bidding system at whichever round the system has reached.

USP Students

  • USP students will follow the distribution of points for Programme and General accounts, which is applicable to the Faculty they are attached to. The instructions for bidding are also applicable to them. USP students will bid for First-Tier modules (or Level 2000 Inquiry tier modules) using the General account.

  • They will bid for the Advanced Course-Based modules (CBMs) or the USP Multidisciplinary Seminar modules (UMSs) (or Level 3000 and above) using the Programme account. USP students will not be required to bid for newly-designed Independent Study Modules (ISMs) as each ISM is a contract between a supervisor and the student. For this, students will need to reserve 1 bid point in their Programme account for each newly-designed ISM successfully registered. On the other hand, students who intend to read ISMs that ride on the regular NUS modules (ride-on ISMs) should bid for the regular module as per normal bidding procedures.

Incoming Non-Graduating Students

  • Incoming non-graduating students will register their modules through Registrar's Office and will not participate in bidding. This practice may be reviewed when the number of such students increases.

Returning Student Exchange Programme Students

  • The following instructions concern NUS students away on SEP for one semester (or longer) and who plan to resume their candidature at NUS campus in the following semester.

  • SEP students must bid for modules to be offered for the following semester (i.e. the semester when they will be back at NUS).

    • SEP students must follow the bidding schedule for the following semester like all non-SEP students.

    • Some students returning from SEP may need to use their SEP modules as pre-requisites to qualify for NUS modules to be read upon return. However, the SEP institution may delay releasing exam results. Students who are affected in this manner are expected to liaise with the teaching departments (NUS) to arrange for special waivers. If it turns out that the pre-requisites cannot be met anyway, but the NUS module has been allocated to the students as a result of successful bidding, the module registration will be cancelled, and the bid points refunded in full.

Partial SEP (Local) Students

  • Students who are on partial SEP (i.e. reading at least one module at NUS) will be allocated 50% of bid points to be distributed into the 2 accounts based on the curriculum structure of faculty/school as approved by Senate.

Full SEP Students

  • Students who are on full SEP will NOT be allocated any bid points for the semester(s) they are on exchange. However, due to different academic calendars in some of the overseas universities, some NUS students may leave for their overseas SEP after the NUS semester commences. For these students whose status in the student database at the time of the online registration is still 'current', they can bid for modules with the points allocated to their Programme and General accounts. But once they leave for the SEP and their student status is changed to 'On Exchange', the modules in their student records and the balance of the bid points in their accounts for that semester will be deleted.

SEP Language Programme Students

  • Students registered with the SEP language programme of the International Relations Office (IRO) should liaise (before bidding begins) with the Centre for Language Studies (CLS) regarding their language modules for each semester. NUS Overseas Colleges The University regards the Overseas College as a residential programme different from the SEP. As such, students participating in the overseas college may be allocated bidding points like other students in residence.

Part-Time Undergraduate Students

  • Part-time students will be allocated a percentage of the 1000 points based on their workload, divided between 2 accounts.

Students on Industrial Attachment

  • Students who participate in industrial attachments for a full semester and do not enroll in any modules will NOT be allocated any bid points for that semester.

Graduate Students

  • Graduate students who wish to opt for undergraduate modules will register through departments. At this stage, they are not required to bid.

Non-Modular Faculty Students

  1. Faculty of Law

    With effect from AY2008/09, students from the Faculty of Law are allowed to opt for a Minor from the Facultys list of approved minors (refer to the Faculty of Law website). In view of this, 1st, 2nd and 3rd year students in AY2008/09 will be allocated 200, 600, 1000 points respectively in their General account. The 4th year students will be allocated 200 points. The students will also need to follow the bidding schedule to bid for any module that they wish to register for. Any balance of unused points will be carried over to the next semester.

  2. Faculty of Medicine and Faculty of Dentistry

Students from the Faculty of Medicine and Faculty of Dentistry who wish to read other faculty/departments modules can do so through manual registration with the faculty/department offering the respective modules.

Students who are unsuccessful in Qualifying English Test (QET)

  • Students who are not exempted by their QET results and required to do ES1000 or ES1102/ES1103* will participate in the CORS bidding exercise and BID for the required modules.
  • Students are to bid for ES1000 and ES1102 using points from the G account. Students are to bid for ES1103* using points from the P account. The points will be fully refunded at the beginning of the following semester upon successful completion of ES1000 and ES1102. Points will NOT be refunded for ES1103.
  • ES1000 and ES1102 will not be counted in the workload computation whereas ES1103 will be counted in the workload computation.
* Students who matriculated in AY2016/17 and after are required to read ES1103. Students who matriculated in AY2015/16 and before will continue to read ES1102.

Students on Leave of Absence

  • Students who are on leave of absence will NOT be allocated any bid points.

Transfer Students

  • Transfer students will be regarded as new students for 2 consecutive semesters in their new faculty. For example: Transfer students who begin their first semester in the new faculty in sem 1, AY 2005-2006 will enjoy protection for designated bidding rounds as new students in the new faculty for both sem 1 and sem 2, AY 2005-2006.

  • If a student transfers on a clean slate, new points will be allocated based on the curriculum of the new faculty. For a student who transfers with credit from one faculty to another, the balance of bidding points in each account will be carried over from Programme to Programme and General to General accounts respectively. This will apply irrespective of the difference in the curriculum structure of the two faculties.


  • Some faculties may allow their undergraduate students to read graduate modules (level-5000 and level-6000) by bidding for them. Some faculties may allow their students to do so by registering manually at the department offering the graduate modules. For such cases, a minimum of 1 bid point will be deducted from the relevant account if student is successful. Students who are interested to read graduate modules should check with their faculties whether they should bid for these modules or register for them manually.
Account Types

Programme and General Accounts

Students will bid for modules listed in 2 separate accounts, namely the Programme Account and the General Account.

Allocation of Points

Students will be allocated 1,000 points in each semester, to be distributed into the 2 accounts based on the curriculum structure of the faculty/school as approved by the Senate.

Please refer to the following table for points allocated to student depending on their faculty.


FoE + SDE + DDP + Nursing + YSTCM

SoC + BiZ


600 400 750 250
Cohort 2014 & before
Cohort 2015 onwards
0 200

Bid points not utilized will be carried over to the next semester, in the respective accounts. Bid points will not have value outside the bidding system and are non-transferable between the 2 accounts.

Programme Account lists:

  • Modules from student's home faculty/school to fulfil Programme requirements (that is, Faculty and Major requirements) and Unrestricted electives (UE) requirements.

  • Modules from student's home faculty/school to fulfil minor requirements.

  • Modules from outside student's faculty/school only if the modules are computed as part of the programme requirements of that faculty/school as approved by Senate. These modules are called "service" modules.

General Account lists:

  • General Education modules (GEM), Singapore Studies modules (SS) and breadth modules to fulfill University Level Requirements (ULR).

  • Modules from outside student's faculty/school to fulfil UE requirements.

  • Modules from outside student's faculty/school to fulfil minor requirements.


To ensure fairness in bidding across all Faculties, a workload policy is in place in the first two rounds of bidding so that all students, regardless of which Faculty they are from, are given an equal chance in securing their choice modules during these rounds.

In this regard, the current workload policy is set at 23 MCs.

From Round 3 onwards, students can continue to bid for additional modules under the maximum workload policy as set by their individual Faculty. Students are strongly advised to seek approval from their respective Faculty if they wish to exceed the maximum workload allowed.

Here’s an example to illustrate this:

Assuming you have bid for 5 modules in the first 2 rounds, 4 of them are 4MCs modules, 1 is a 5MCs module. -> Total workload = 21 MCs, which is still within the cap of 23 MCs for the first two rounds of bidding.

If your Faculty has configured the maximum workload policy as 25 MCs, you will be allowed to bid for a 6th module in Round 3. Therefore, total workload = 25 MCs.

For minimum workload, please refer to information here: http://nus.edu.sg/registrar/edu/UG/graduation.html#ResidencyRequirement


Module Registration


The quota of each module for each bidding round will be made known before each round begins. This means that the quota for modules in Round 1A will be available in Round 0. The quota for modules in Round 1B will be available when the results of Round 1A are released and so on for each round. Information about quota for each round cannot be released earlier because the remaining vacancies from a previous round, if any, will be rolled over to the next round. Students may only bid when the bidding round begins although they may place advance bids in earlier rounds.

Students MUST make sure that they meet the necessary pre-requisites and timetables (lecture, exam and tutorial if available) before bidding for their modules.

The minimum bid for any module is 1 point. Students must make sure that they have enough to bid for modules in each round. They will bid for modules every semester.

Students should complete all their bidding transactions early. Early bidding allows time for further research, changes or queries.

Students should make a printout of their bids prior to leaving the system - this is the receipt. Keep records of all transactions.

As students pay the lowest successful bid, any unused bid points after each round will lie idle and will simply be carried over to the next bidding round.

Students should bid according to the value that they place on the module, in relation to the total bid points at their disposal in each account for each round.


  • Click on CORS User Guides to get a sense of how the system works.

  • Read the instructions for online registration and the schedule for the various bidding rounds carefully.

  • If students have been successful in their bidding, there is no need to confirm (their acceptance for) the modules.

  • Students whose bids are unsuccessful should ensure that the bid points that have been used for bidding are refunded in the respective accounts. Students may either bid for the same module if vacancies are still available or bid for other modules in the next round.

  • Students who encounter any problems using the CORS may e-mail to the CORS helpdesk: corshelp@nus.edu.sg which is coordinated by the Registrar's Office with participation by faculties/schools. Students may also call the CORS helpdesk (only available during registration period). Students should refer to the CORS website for the hotline number each semester.


The allocation of modules is based on the bid points placed for each module at each round. If there is a tie in the bid points, the outcome will be based on first come first served. Students pay the lowest successful bid. If supply exceeds demand for a module for any bidding round, the lowest successful bid will be 1 bidding point. Unsuccessful bidders will be fully refunded.

Before a student can bid for any module, the first step is to select a module. If a module that is selected has more than one lecture group, the desired lecture group must also be selected. The system will then check that the pre-requisites have been fulfilled and there are no lecture or examination timetable clashes with the other modules the student has selected or has been pre-allocated. To facilitate explanation, there will be no reference to lecture group below.

After a student has selected the module, the confirmation screen will indicate whether the student should be bidding from the Programme or General account.

For faculties with Lecture-Tutorial (L-T) package, for example, classes with small enrolments, the L-T package will be published as an L-T slot for bidding.

Students are only allowed to read the module if they are able to satisfy the time slots for both lecture and tutorial groups. This also applies to sectional classes for Human Resource Management (HRM).


There are 3 phases of bidding for each module. These are advance, open and close. Students get to participate in each of these phases for each module, but the timing of each phase varies from student to student. Why? Often, students enroll in the same module even though they are also enrolled at the same time in different degree programmes, different majors or different minors. Each module will step through advance, open and close bidding phases with reference to the status of a student. The example below is an illustration.

Illustration: Let's take the example of a chemistry module that is essential to a chemistry major student. At round 0, all students (major and non-major) get to place advance bids for this chemistry module. At round 1A and round 1B (when only major students get to bid), a chemistry major student can participate in open and subsequently close bidding. A Science Faculty student who is not a chemistry major cannot participate in open and close bidding in round 1A and round 1B. However, at round 2A, open and close bidding will be available to all students from the Faculty of Science (chemistry majors and non majors).

Advance Bidding

As the name indicates, advance bidding facilitates those students who wish to place a bid for a module or several modules ahead of the bidding period identified in the bidding schedule. In this way, students need not return to bid as each round begins. However, it will be assumed that students who stick to their advance bids will not be planning to adjust them. (Adjustment of bids is available during the time limit set for each bidding period.)

All students can participate in advance bidding at round 0 for all modules that are offered for bidding for the semester. Students can also participate in advance bidding in other rounds when they are not eligible to participate in open and close bidding yet. Please note that there is also possibility that module is fully subscribed in the current bidding round and therefore only advance bidding is available for that module. For advance bidding, place any bid amount. As for all bid phases, the bid limit will only be subject to the amount of bid points at a student's disposal in the relevant account. After placing an advance bid, a student can still increase it subsequently or withdraw it for re-submission at a lower or higher bid. The advance bids will not be considered in the allocation of modules at the same round with the bid points placed by other students eligible for the open or close phases.

Once a student becomes eligible for the open bidding phase of the module, the system will transfer the student's advance bid to the open bidding queue.

Illustration: To return to the example of the chemistry module, a non-chemistry major student from the Faculty of Science can place an advance bid for the chemistry module in rounds 0, 1A or 1B. The system will allocate places for the chemistry module at the end of rounds 1A and 1B for chemistry major students only. The advance bid of the non-chemistry major will not be considered because the non-chemistry major student is not eligible for open or close bidding at rounds 1A or 1B. However, the system will transfer the advance bid to the open bidding phase in round 2A when this non-chemistry major student becomes eligible, and the allocation of places for round 2A will take his / her bid into consideration.

Open Bidding

During open bidding, students place their bids or adjust their bids within the period indicated in the bidding schedule. CORS will provide basic information about the bids being placed. The number of bidders, highest, lowest and the next successful bids will be displayed.

During the open bidding phase, a student can find out whether his / her bid for a module is still successful at a certain moment in time, or is in danger of being pushed out of range by other bidders. Such information enables a student to adjust his / her bid so as to maintain his / her rank in the queue. The student can decide to increase his / her bid. To decrease the bid, the student has to withdraw the bid and re-submit a new bid. During the open bidding phase, the system will keep students informed about the next minimum successful bid. The next minimum successful bid is the minimum bid points that are needed to be successful, but this minimum is subject to constant change in a dynamic situation.

Illustration: To return to the example of the chemistry module, different students are eligible for the open bidding phase at different rounds. The chemistry major students from the Faculty of Science are eligible for open bidding in rounds 1A, 1B and 2A (and also subsequent rounds). For the non-chemistry major students from the Science Faculty, their eligibility does not kick in till round 2A onwards.

Close Bidding

Close bidding kicks in just before the bidding period ends. Typically, if a bidding period extends more than 7 hours, the closure is invoked 2 hours before the bidding period ends. If a bidding period is less than 7 hours, the closure is invoked 30 minutes before the bidding period ends. During the close bidding, students can still place their bids for modules as for open bidding, except that CORS will not release any information about the bids that have been placed. The purpose of the close bidding is to discourage students from delaying their bids till the last moment, hoping to out-bid competitors. Students can still place bids during the close bidding phase. They can also increase their bid amounts or withdraw their bids.

Students cannot view individual bids made by other students while the online registration is in progress. The bidding history, including the individual bid points without names, will be published together with module allocation results for each round.

Module Allocation

Once the period for the bidding round ends, the system will take over to allocate module places to successful bidders based on the bid points. As stated earlier, advance bids will not be considered. Only open and close bids will be considered. If there is "n" number of vacancies, and the number of bidders is more than "n", then the top "n" bidders will be declared successful.

The allocation is based on a first-come first-served basis. Please take note also that when you change your bid after you submit your first bid for the module, your bid timing will be changed to the time where you have last updated your bid. In situations where there is a tie, i.e., some students placed the same successful bid point, those who placed the bid earlier will be allocated the module first.

For students who put their entire bid points for a module when there is only 1 quota left and there is more than 1 bidder for that module, s/he will have to pay the entire bid points that s/he has placed for that module. This is because the maximum bid point is also the lowest successful bid point in this special case. Therefore, you are advised to think carefully before placing your entire bid points for a module.

The NUSNET email facility will be used to notify students about the results of the module allocation exercise, whether successful or not.


Declaring and Changing Major/ Minor/ Stream/ Area of concentration

Students are allowed to declare major/minor/stream/area of concentration if they have not already done so. They are also allowed to change major/minor/stream/area of concentration. However, this can only be done once during each online registration exercise. Therefore, it is important that students make up their minds about their major/minor/stream/area of concentration before making declarations on the screen. The earlier students declare their major/minor/stream/area of concentration, the earlier students will enjoy "protection" in their major/minor/stream/area of concentration modules.

Students can still change major/minor/stream/ area of concentration after each online registration exercise is over. Students should check with their faculty on which semester they are required to declare their major/minor/stream/area of concentration.

Changing Bid Points

Students are allowed to increase the bid points for modules during the time limit allowed for each bidding round. Within the same period, students may also reduce the bid points by withdrawing and then re-submitting a new bid.

Changing the Lecture Group

If students decide to change to a different lecture group, they will have to drop the module (the refunds policy will apply) and bid again for another lecture group.

Suspending a Module

For various reasons, a module that has been placed for bidding may have to be suspended. When this occurs, an email regarding suspension of the affected module will be sent to students. Various scenarios may arise when a module is suspended, with different outcomes.

Various scenarios


Resumption of bidding

  • All bids made before suspension are still valid.
  • Students may resume bidding after suspension is lifted.

Voiding all bids placed before suspension

  • All bids made before suspension are void and will be cleared.
  • Students have to make a new bid for the module.

Delisting of module

  • All bid points will be cleared.
  • Students have to select another module for bidding.


Delisting Modules after Successful Allocation

If a module is delisted due to low enrolment, an email regarding the delisted module will be sent to students. The module will be removed from student's allocated modules and the bid points will be fully refunded.


Although modules may be cross-listed (e.g. GEM1234/PS1234), students bid under one module code only. Conversion to the cross-listed code will not normally be considered. If conversion is the only way for students to meet graduation requirements, such a conversion can only be considered after File for Graduation (FFG) and not earlier. If conversion is approved, a conversion fee of 30 bidding points will be levied from the relevant account.

Dropping an Allocated Module

Students are allowed to drop an allocated module as long as the module is not flagged as 'non-droppable'. The refunds policy will apply.

Changing the Lecture Group

Please refer to the “Appeal - Changing the Lecture Group” section under the Appeal tab.

Tutorial Registration

For ease of reference, the term "tutorial" will also include discussion groups, language classes, laboratory sessions, practical classes, etc.

It will be the generic term used to describe any activities that students participate when they meet, in addition to attendance to lectures to fulfill the module requirement.

Please note the following:

  • Tutorial allocation will take place after the module registration has ended.

  • Tutorial groups are allocated by balloting and not by bidding. The allocation of tutorial groups is an exercise that is separate from the allocation of modules by bidding.

  • Students should refer to the Registration Schedule for the dates of each tutorial round.

  • It is the student's responsibility to attend the tutorial group in which he/she is registered. Failure to do so may result in being marked "absent" (with possible consequences for examination grading).

  • For cross-listed modules that do not have tutorial groups of their own, please check the tutorial groups under the parent code even though you have registered under the cross-listed module code.

  • A tutorial group may be cancelled if tutorial enrollment for the group is low. If students cannot find a suitable tutorial group, they may be required to drop the module and be asked to identify an alternative module with vacancies.

  • Students who read modules offered by the Faculty of Arts and Social Sciences have to register for tutorial groups for their modules. Otherwise, the Faculty will withdraw the module with a ‘W’ grade in Week 5 of the semester.


Tutorial registration consists of the following different stages:

  1. Balloting (Multiple Rounds)
  2. Add / Drop
  3. Swapping
  4. Manual (walk-in) registration at departments


  • For each round, a student is asked to rank 20 preferences for tutorial time slots for all the modules he/she is enrolled.

  • A student may list fewer than 20 ranked preferences, but this means there are fewer preferences for the system to consider. A shorter list of preferences may also mean that a student may not be successful in getting a tutorial allocated at all.

  • However, a student must ensure that there are no tutorial timetable clashes between the ranked preferences and his/her existing schedule.

  • If, despite the provision of 20 ranked preferences, the student is still not successful in being allocated the tutorial groups for all his/her modules, the student will be asked to revise his/her preferences and re-submit the list of 20 ranked preferences for further balloting.

2) Add/Drop

  • The "add/drop" process begins after the last round of tutorial balloting. Students can add any tutorial class on a first-come-first-served basis as long as there are still vacancies.

  • When a student adds a new tutorial class successfully, his/her place in the current class will be withdrawn, and the vacancy thus created will be released to other students.

3) Swapping

  • The swapping process begins after the last round of tutorial balloting. Let's assume a student has already been successfully allocated a tutorial class but he/she would like to change to another class that is currently full.

  • He/she can post a swap request for the attention of those students in the full tutorial class. Perhaps there is a student from the full tutorial class who wants to make a corresponding switch.

  • A swap will then take place. If not, the request will be stored in the system until a time when a corresponding match is found. Students will be informed of a successful swap by email.

  • If a student changes his/her mind and decides to remain in the tutorial class originally allocated, he /she must remember to cancel the request to swap before the swap gets to work its way through.

4) Manual (walk-in) Registration at Departments

  • Appeals to departments should only be filed after the student has tried but failed to secure a suitable tutorial time slot using the above-listed methods. Students should note that they can appeal only for tutorial groups with vacancies. The departments will not accommodate students who regard manual (walk-in) registration as the first course of action instead of balloting, add/drop and swapping.

  • At the end of the tutorial registration (ie at manual (walk-in) tutorial registration), a student who still cannot enrol in a tutorial / discussion group due to timetable clashes will be allowed to drop the module and given a full refund.

  • The usual refunds practice will apply to all other cases where modules are dropped.


  • A student will bid for modules to satisfy his/her minor using the Programme Account if the modules are offered by his/her own faculty.

  • For modules offered outside his/her faculty/school, the student will bid using the General Account.

  • There are 2 types of minors offered - Restricted Minor and Open Minor.


  • Students will need to apply for this minor at the faculty/school concerned.

  • While some of the minor modules may be prescribed/pre-allocated, students may be required to bid if a basket of minor modules are available to them.


  • Students do not need to apply for this minor at the faculty/school concerned.

  • Students read the relevant minor modules and count it towards their minor requirements when they file for graduation. Declaration of Open Minor will not guarantee the enrolment in the modules. Students will still have to bid for these modules.

Refund Policies


Activity Period % of bid points to be refunded
Register for or add new module (s) Check CORS bidding schedule Not applicable
Drop during module registration period Anytime before the drop with 'W' grade takes effect. 50%
(Note: In cases where refunds involve decimal points, the bid points will be rounded down to the nearest whole number)
Drop with 'W' grade Check CORS bidding schedule for commencement of 'W' grade period. The last day of 'W' grade period is also the last day of the mid-semester break. 0%
Drop with 'F' grade 'F' grade takes effect on the 1st day of week 7 onwards. Week 7 commences when the mid-semester break terminates. 100%

Please refer to the academic calendar for the dates of the 'W' grade and 'F' grade periods.


Students will be given a full refund of bid points (before the next semester begins) if they have the following grades in the previous semester:

  • 'F' grade

  • 'IC' (incomplete) grade


    Students can file in appeals to address problems which arise in the course of bidding. As far as possible, all appeals should be filed online through CORS. For some appeals relating to the waiver of pre-requisites, students may be required to submit hard-copy documents such as A-Level equivalent results for verification purposes.

    Once an appeal is filed, an email will be generated and sent to the relevant staff (in the faculty/school/department) for his/her review. For certain appeals, approval from an external party, such as a lecturer, may be required. Once the decision is reached, the faculty/department administrator will update CORS and an email is automatically sent to the student, notifying him/her of the result (see flowchart for more details.)

    The Appeal Handling Chart (Online Appeals) shows the different appeal types and which faculty the respective appeal will be routed to for processing. Student appellants should note that the categories of appeals were set up to facilitate efficient handling. Please use them as far as applicable; try not to overload the "Others" category.

    Students who ignore the appeals categories or do not use the appropriate online appeal forms will disadvantage themselves. The system attaches the relevant student data to each appeal form so that the administrator has enough information to decide on the appeal. Students who send appeals via their personal email accounts shall experience and expect delays as relevant information may not be available to process.


    For appeals which involve adding a module, an average bid point will be charged for successful appeals. The average bid point is the weighted average of all the lowest successful bid points in each round. CORS also reserves the right to levy administrative charges (30 bid points from the relevant account) on certain transactions.


    For appeals that involve changing a lecture class, the allocated module will be dropped with 50% refund. An additional 30 points, as an administrative charge, will also be deducted from the students account. A further charge of the average successful bid points of the lecture class that is swapped, will be imposed.


  • Appeal is either module related or non-module related.

  • Appeal authority is the faculty or department where the appeal will be routed to.

  • Selecting the correct appeal type can help shorten the processing time.

  • Home faculty/department refers to the faculty/department that the student belongs to.

  • Host faculty/department refers to the faculty/department that is offering the module.
