Everyone is different. Just do what you can as soon as possible and you'll be fine. I know a few people who got over 95 and they weren't consistantly studious.
I've been hanging around a while just lurking (LOL) and it doesnt say anywhere that you are doing a phd. It looks like you're making it up just to impress a girl over the nternet. Cool ...
haha okay we both think she's cool.
I wouldn't give a troll like that your account though, but that's just me. Lol he probably is some 40yo seedy old guy trying to get a 12yo looking girl.
