>>1 Like Misu, I don't really believe there's any formula. Just read over whatever you have to until you get it. There should be mock tests at the end of each chapter in your books, right? I suggest taking them. They're a really great way to tell how much you do and don't understand/remember. Once you know that, you can make those things the basis of your studying. The night before a test/quiz, quickly read through/scan over that chapter's notes.
I think you should be good with that. Unfortunately, I can't say much more since I've never properly studied before.
And on that note...
>>3 I generally don't study but get A's and B's on tests, as well... :|
But then again, I'm one of those weirdos who
actually pays attention during class. If you pay attention and retain what you learn during class, you don't need to waste your time studying afterwards.
The only thing I do particularly bad in is History, and no matter how much I study, I can never remember that shit. (Although I've been doing rather well this year. I guess being forced to take a lower level History class is actually doing some good. Probably because we don't have to remember dates or names or write unnecessarily long essays about people we never met.)
My grades are mainly affected by my horrible homework habits /shot
