Bug in the Graduation Requirement having done a module that is considered equivalent

[JustinSoh]

Description: After adding all the modules that I have done, and typing the graduate requirement - I see that I am asked to do CS1231 even though I have already completed CS1231S which are equivalent

Steps to Reproduce:

2. Launch the app
3. Run graduate
4. Run view Expected Result: CS1231 is no longer there as I have cleared an equivalent mod before

Actual Result: CS1231 still shows up despite me clearing CS1231S already

Team's Response

While we acknowledge that adding cross-listed/overlapping modules does not update the graduate list for the current iteration of the application, it is not a type.FunctionalityBug as it is expected and should not be classified as severity.High.

By definition, a bug classified as severity.High should be "a problem that affects most users" and "problems that make the product almost unusable for most users". We do not believe that the inability of adding a cross-listed/overlapping module makes the product unusable for most users since we argue that:

1. Users can just add its equivalent that exists in the CEGModule list.
2. The event of having a CEG student taking a cross-listed/overlapping module is slim, hence those students are a minority compared to students taking the recommended ones listed here. Refer to the image attached below regarding reading cross-listed/overlapping modules from the NUS UG FAQ.

Hence we believe that the appropriate severity should be severity.Low since it may "appear in very rare situations and causes minor inconvenience only" in the event a CEG student chooses to read an overlapping course. It does not affect normal operations of the product.
