Wonder when I'll actually persuade myself to start mugging

Exams are nearing, and I shouldn't be thinking too much about it because I get more nervous if I do. For some reason I am actually somewhat worried about physics, that I can't hit 80%. Well I think there is always some random reason why I could not get so high for physics. There has to be this mugging component that gives the teacher a chance to penalise me. The worst is definitely biology. So pressurizing zzz. and so stressful. I took it because I wanted to waste less time slacking in school and maximise time usage. But it simply ended up giving me more stress because there are so many topics to study. It's probably time to let go of what I have, which is always a painful experience. However, it's sth that is inevitable because I have too many opportunities now = more responsibilities and more stress. I actually wonder how meaningful is getting a good MSG requirement, but probably it reflects greatly on one's personality, which deteremines one's fate. I've realised that adaptablility is not enough for a very long time now, and I need sth more, that can bring about change so that people don't have to suffer like me in the future, by that's another 10 more years!!!
