5 Steps To S/U A Module In NUS


As a fresh student of NUS, you might have heard of something known as the S/U option. If you’re like me, you might not have understood what exactly this ‘option’ entailed when it was first mentioned.  

A brief summary for your understanding of what this ‘S/U’ option does is that – depending on your original module grade – you can choose to assign the module either an ‘S’ or ‘U’ grade to replace that original grade. Assigning either of the grades ‘removes’ the module’s original grade from the calculation of your CAP

Thus, it is definitely a nifty tool for you to have to ensure that your CAP is not brought down by modules where you ended up scoring below your expectations

Being something that you’ve probably never heard of or encountered before in Polytechnic or JC, it might be slightly confusing for you at first.

As such, here is a quick guide on how you can go about it!

How to S/U a module in NUS

Important note: S/U declaration can only be done on EduRec.

Here are 5 steps that you should follow to declare your S/U:

  1. Log into EduRec
  2. Go to ‘Academics → Examinations’
  3. Go to ‘Examinations → Submit S/U Declarations’
  4. Go to ‘Declare S/U for Current Term’
  5. Select the modules to S/U and submit

#1 Log into EduRec

To declare your S/U, you will first need to log into NUS EduRec.

#2 Go to ‘Academics → Examinations’

From the homepage, you will then select ‘Academics’.

And then select ‘Examinations’.

image 91

#3 Go to ‘Examinations → Submit S/U Declarations’

From the ‘Examinations’ tab, select ‘Submit S/U Declarations’ from the sidebar.

image 92

You will then be directed to this page, where you should select ‘Undergraduate’.

#4 Go to ‘Declare S/U for Current Term’

Finally, you can then select ‘Declare S/U for Current Term’ to view your modules that can be S/U-ed.

image 94

The number of MC’s that can be S/U-ed from your current term will be displayed at the top after selecting ‘Declare S/U for Current Term’.

image 95

Only the modules that can be S/U-ed will show up at the bottom of your page.

image 96

#5 Select the modules to S/U and submit

After deciding which modules to S/U, select ‘Check to Declare S/U’ and the representative ‘S’ or ‘U’ grade will appear.

image 97

Click on ‘Submit’ to confirm your decision.

image 98

Upon successful S/U declaration, your new grade will be reflected on the same page and the ‘Submit’ option greyed out.

image 99

However, your updated result will not be reflected on your transcript yet.

Your transcript will only be updated around 3 working days after the deadline of the S/U Declaration Exercise – An email notification will be sent out regarding your updated transcript.

Declaring your S/U via uNivUS

You can also make use of the uNivUS app on your mobile device to access EduRec and declare your S/U.

After logging into the app, tap on ‘More’.

image 102

You will then be brought to this page, where you should tap on ‘Academics’ – which will then display the ‘EduRec’ icon.

image 103

Selecting ‘EduRec’ will then direct you to your EduRec homepage, without requiring you to login.

image 104

From there, the steps to declare your S/U are exactly similar to the ones listed above.

There is no difference between whether you choose to declare your S/U using your computer or mobile device. 

As such, it is entirely up to you to choose which is more convenient!

Can I undo my S/U decision?

If you do decide that you wish to undo your S/U decision, you can only do it during the S/U Declaration Exercise.

This is because all declarations outside of the allocated time frame, will be considered as final (as stated on NUS’ website). Thus, you will be unable to make further changes past that period.

So here are the steps that you should follow if you do want to undo your decision:

  1. Access ‘Declare S/U for Current Term’ on EduRec
  2. Uncheck S/U-ed module(s) and submit the new decision

#1 Access ‘Declare S/U for Current Term’ on EduRec

Follow the steps mentioned above for declaring your S/U, and access the ‘Declare S/U for Current Term’ page on EduRec.

image 105

#2 Uncheck S/U-ed module(s) and submit the new decision

Scrolling down, you will see that the module(s) that you have selected to be S/U-ed will have a checkmark.

image 106

Uncheck the box and click on ‘Submit’ to confirm your decision.

image 107

Like the declaration of your S/U, you can also do this via the uNivUS app. The steps for that are also similar.

Which modules can I S/U in NUS?

Important note: If you’re looking to get an in-depth idea of Module S/U eligibility, it can be found here. You will, however, be required to login into your NUS account to access this file as it is only available for NUS students.

Unfortunately, not all modules can be S/U-ed.

As seen, you can only S/U a module if it is a 1000 module or a 2000 module that has no prerequisites. There are definitely exceptions to these cases, and they will be listed below.

Level 1000 modules

All level 1000 modules are eligible for S/U. However, the only exceptions to this are certain 0 modular credit (MC) modules of the CELC and level 1000 Major Study modules of YSTCM.

Here is the list of ineligible CELC modules:

Module CodeModule Name
ES1000Foundation Academic English
EM1201English for Academic Purposes 1 (Music)
EM1202English for Academic Purposes 2 (Music)

Here is the list of ineligible YSTCM modules:

Module CodeModule Name
MUA1101Composition Major Study 1A
MUA1102Composition Major Study 1B
MUA1161Foundational Studies on Principal Instrument
MUA1162Juried Performance Presentation
MUA1168Foundational Area Study 1
MUA1169Foundational Area Study 2
MUA1190Applied Voice Major Study 1A
MUA1191Applied Voice Major Studies 1B

This does mean that the GE modules which you will be required to takesuch as GEA1000 or ES1103 (which I have reviewed: GEA1000, ES1103)can be S/U-ed

This can be considered as good news as that it means you can choose to focus more on your Major Study modules instead of your GE modulessince you will be able to S/U them!

Level 2000 Modules (No prerequisites)

All level 2000 modules can be S/U-ed if they did not have any prerequisite modules. The only exceptions to this are certain USP modules.

Here is the list of USP modules ineligible for S/U:

Module CodeModule Name
UWC2101%Writing and Critical Thinking
UQF2101%Quantitative Reasoning Foundation

Level 2000 Modules (Prerequisites)

Level 2000 modules that have prerequisite modules cannot be S/U-ed. However, there are certain exceptions, as listed below.

Here is the list of eligible level 2000 modules:

Module CodeModule Name
UTW20001%Ideas and Exposition
CS2101Effective Communication for Computing Professionals
ENV2302Communications for Environmental Studies 
ES2002Business Communication for Leaders (BBA)
ES2007DProfessional Communication
ES2531Critical Thinking And Writing
ES2660Communicating in the Information Age
IS2101Business and Technical Communication
MUL2107French for Musicians 1
MUL2109German for Musicians 1
MA2001Linear Algebra I

Level 3000/4000 modules

Level 3000 and 4000 modules cannot be S/U-ed as well.

Other situations where the S/U cannot be applied

There are specific scenarios as stated, that will render you unable to declare S/U for a specific module even if they are S/U-able.

image 109
Screenshot from Module Eligibility pdf

As seen from the screenshot, a module cannot be S/U-ed if:

  • The module was assigned an ‘IC’ grade
  • The student had withdrawn from the module, being assigned a ‘W’ or ‘F’ grade
  • The student was caught for plagiarism
  • The grade was assigned by the Board of Discipline

Is there an easy way to identify which modules I can S/U?

Currently, the most efficient way for you to find out which modules can be S/U-ed is through NUSMods. This is done by checking the ‘Additional Information’ section.

image 110

Using this screenshot of HSA1000 from NUSMods as an example, you can see that the ‘Additional Information’ section states that this module has a S/U option. This thus indicates that this module can be S/U-ed. 

As such, as long as your module of interest is stated to have a S/U option, it would be safe for you to assume that it can be S/U-ed.

NUSMods would probably be your best choice, as currently, there is no filter that can be used to sort out which modules can or cannot be S/U-ed. 

When do I need to declare my S/U in NUS?

As stated by NUS, the S/U Declaration Exercise only lasts for 3 days from the release of your exam results – inclusive of the day your results are released.

image 111
Email from NUS

For example, for AY21/22 Semester 1, our results were released on 21st December and the S/U Declaration Exercise lasted for 3 days – till 23rd December 6 pm.

If you try to S/U outside of the allocated days, you will be met with the following message – “The S/U Declaration System is currently unavailable. Please refer to the University timeline on the opening and closing of the S/U Declaration Period.”

image 112

Can I S/U modules from my previous semester or just the current one?

In previous academic years, you could only S/U modules from your current semester.

image 113

However, as of the 13th of December 2021, NUS has made changes to the S/U Declaration Exercisebeginning from AY21/22.

image 114

With a new S/U system, you will now be able to S/U modules from the current semester and the previous semester of the same academic year.

As such, you will be able to declare S/U for modules that you took in Semester 1, during the S/U Declaration Exercise of Semester 2.

How many S/Us can I use each semester?

Source: NUS

In your first 2 semesters (freshman year), you will be able to exercise the S/U option for up to 32 MCs, equating to around 8 4 MC modules.

However, if you do not use up this 32 MC quota in your freshman year, you will be allowed to carry over the remaining MC quotaup to 12 MCs – to be used in your subsequent years.

Thus, in your life at NUS, you will only be able to S/U up to 32 MCs. And out of this 32 MC quota, you will only be able to bring over 12 MCs into your 2nd year and onwards.

As such, the general consensus that I’ve heard from classmates is that ideally, you do want to aim to only use 20 MCs of S/U in your freshman year so that you can bring over 12 MCs to be used in your upcoming years.

S/U-ing modules is an important strategy, particularly if you are intending to obtain first-class honours.


The S/U option is an extremely helpful tool to have during your university education. Being able to ‘remove’ grades that can otherwise pull down your cap, is definitely lifesaving

Moreover, with the new changes to the S/U option, it is definitely even more beneficial to you now. Being able to wait till the end of Semester 2 to then decide if you want to S/U modules from Semester 1, is something unheard of previously.

As such, you can take full advantage of this perk granted to us and I hope this guide has helped clarify any questions you might have had!
