All I can say is start preparing early.
Math 1za3: brutal exam just because there was a lot of series and sequences (ch 11) and few of the other material. There was a definite bell curve in that course.
Physics 1d03: I didn’t like physics that much , but if u at least go over the capa then the short answer section shouldn't be brutal for u. If u did the capa throughout the term, u should be fine (yea you can get a 60%). Multiple choice was kindda tricky to be honest.
Chem 1e03: umm class avg for that exam was 65% for us. It wasn’t easy , I can’t really elaborate on that exam, I found it hard, but what helped me pass was that I did the samples that he posted on avenue. I am pretty sure they are helpful.
If you start preparing early , then you should be fine. If you understand series and sequences in math u can do good in the exam. I just found them confusing.
That’s all I have to say, its 3 am , sorry I am half-asleep lol, but hopefully that will at least give u an idea on what to expect.
Good luck
