I absolutely agree that Going to Class is the #1 key to doing well in college. Additionally, find out what your learning style is. The three types are Visual, Auditory, and Kinesthetic. Personally, I lean very strongly toward Auditory, so I learn easily by listening to a lecture or hearing something described, but find it difficult to learn from reading. I religiously attended class in college because I knew that listening to the lecture was the only way I'd learn. I didn't read one textbook through all of undergrad or grad school (I did/do read - but only more creative non-fiction; textbooks are DRY!). Let me just say I did exceptionally well in college, which I attribute to knowing HOW to learn. If you know HOW you learn, you can cut back the number of hours spent studying, because when you study you'll be much more efficient about it.
