Test Week stinks

I'm in my test week currently, first three papers are the ones that I thought I knew better, but I guess I didn't manage do well either. Didn't prepare well enough, didn't work hard enough, haha, I guess we harvest what we sow huh? Haha... Left with 2 modules which I've got no idea what is it about, OOP isn't that bad, at least I know simple multiple choices questions. Mechanics is the problem, totally got no idea how to solve the questions. Argh!!! Can't wait for Friday!
