I heard the same thing too. And I don't really know the reason. I'm
quoting this from one of my previous threads. It was made by
bizzkit0102:
"I heard exam timetables in NTU are generally better spread
out than NUS. It's like lets say you take the same number of
modules for a similar course in both universities, NTU's exams will
tend to spread over 2-3 weeks (unless you screw up by repeating too
many subjects) but in NUS, chances are it'll be done and
dusted in 1 week. So more stress. There's a saying that goes, in
NUS, people ask one another, you get A or B for your subjects. In
NTU, it is you got "pao" (repeat) your subject anot?"
This is true. NTU exams are generally spread over 3 weeks so its
quite rare to have back to back papers unless you planned it that
way. Personally i have exams on 16, 17, 21, 22, 27. Not exactly the
best timetable but still some gaps.
NUS exams are all finished in a week so its more stressful
studying everything together.
