on a serious note, since you sound like a serious guy, asked a serious question and probably want a serious answer, i would say get rid of your user name, get rid of your membership on YWN, and if you dont, at least stay the way you were before; no posting, only reading.
that aside…
-you have to pace yourself. you may have heard this a bunch of times, because its the only way.
-dont procrastinate. if you really wanna get down to business, and you sound like you do, it’ll be easier for you to find the spare time in between classes, on your lunch break, stuck in traffic etc. to study, review…
