<p>Depends on the class. I think Curt and I have the same teacher - discounting time spent in class, I spent maybe two hours overall on English and got a 98%.</p>
<p>My psychology class, about the same. I studied a bit in the beginning when there were a lot of new concepts but after that didn’t bother. Also got an A.</p>
<p>Math, meh. Studied maybe an hour a week, averging out the weeks I didn’t study at all due to knowing the concepts. Should have studied more. Got a B, but I think the professor forgot to drop my lowest score. Ah well. Doesn’t count towards my GPA.</p>
<p>BIOLOGY. I studied two hours a day, every day. Not including all day study sessions towards Finals. Because I did poorly in the lab section I ended up with a B. Otherwise I consistently did the best in the class.</p>
<p>I said all that to say this; trust your gut. You know what you don’t understand, what you need to work on. If chem is easy, don’t waste your valuable tim on it. If you get sweaty palms just thinking about your history class, study all the time.</p>
