Re: how
I usually studied in a panic mode. I always made a big deal right before the exams and made myself think that everyone else was done.
Jafri staying after is school so much better, I used that method to study for really hard exams and stayed afterwords in the library sometimes to study for them.
For some of my other exams I studied in groups, we all used to go to this cafe to study, it was fun :)
