I really appreciate all the advices that you mentioned. When I was still a student, I am allowing time for final examination. For me, it is a make or break situation as a student because that is the moment where I will get the chance to know if I will pass or fail. Well, it's every student's obligation to review or make preparations for final examination in order for them to advance. There are smart students who can pass without reviewing, but there are also some who need time to review a lot for them to make it!
