NUS Internal Blended Learning Online Courses (iBLOCs) for Returning Full-Time National Service (NS) men

iBLOCs are mounted from January 2023 to cater to Returning Full-Time National Servicemen (NSmen) who wish to have a head start in university education and more time to transit to academic life. NUS welcomes NSmen who have places reserved for them in NUS and will be matriculating as undergraduates in August 2023 to apply for iBLOCs, if they wish.

Notes. A foundation module is usually a Level-1000 module which helps to provide foundational training to students before they move on to higher level modules, in subsequent years in their course of study.  A bridging module is to help those without specific ‘A’-Levels modules, to put them on par with those who might have already done so at ‘A’-Level – for example, MA1301X helps students without ‘A’– Level mathematics. 

3) Modules Application

Applicants can apply for the iBLOCs they would like to read through the NUS Online Application Portal. Please consult the user guide on how to submit an application for iBLOCs through the NUS Online Application Portal.

k Exercise

Students are encouraged to participate in the Online Student Feedback Exercise as it is an important element of the University's process for quality assurance of education. Students will be notified of the specific dates of the Student Feedback Exercise in due course.

8) Access iBLOC Course Materials

All students will have an email account at NUS that will be their official point of contact. Most communications from NUS to students will be via the official email account. To access your NUS email account, proceed to NUS home page at and click on 'EMAIL', located on the top right hand corner of the webpage. Students who are taking iBLOCs from January to June 2023 as a Non-Graduating student will receive Welcome emails from your instructors. Hence it is important that students check their NUS email account at the start of the course on 9 January 2023.

Students must complete their online Registration (Part One) and change their default NUSNET password before logging into the portal. To access the LumiNUS, click on NUS User Login. At the organization sign-in page, please enter your user ID as 'nusstu\your NUSNET user ID' followed by your new NUSNET password.

9) Advanced placement credits with grade

According to the University’s Advanced Placement Credits (APC) Policy, upon admission, you may apply for the iBLOC(s) to be transferred into your undergraduate (UG) student record as Advanced Placement Credits with Grade (APG) if you satisfy the criteria of obtaining D grade or above for the module. With the APG, the grade and credits earned will be computed into your Cumulative Average Point (CAP). However, you may choose to exercise the Satisfactory/Unsatisfactory (S/U) grading option for the module (if eligible) during the S/U option exercise conducted upon results release at the end of Semester 1, AY2023/2024 together with your other Semester 1 modules. Modules for which students have opted for S/U grading will not impact the CAP and the letter grade will not be shown on the transcript. An 'S' grade will be assigned if you obtain a grade of D or better (i.e., grade point of 1.0 and above); a 'U' grade will be assigned if the grade obtained is lower than a D grade. You will only receive credit towards the degree if you attain a 'Satisfactory' (S) grade and a module with a 'U' grade earns no credit. You should refer to the policies relating to the Grade-free scheme and the number of modular credits which can be taken on an S/U basis here. The S/U option will apply to all Level 1000 modules (with or without pre-requisites) and Level 2000 modules without other NUS modules as pre-requisites, unless otherwise stipulated by the Faculties/Departments.

After the release of examination results, Registrar’s Office will contact students who are eligible for the APG via email to inform them that they may apply to transfer the module(s) which they have achieved a D grade or above.
