It's part of the college experience to find out your study style. Some can pull all-nighters, some sleep early and get up early, some take caffeine pills or drink lots of coffee, some don't study and just give up, others go to the 24 hr study room (which will be full), and others do whatever.
After a couple of quarters, you'll find something that works for you. Personally, I couldn't do the cramming nor staying up all night, so I started actually studying and keeping up with the class. Come midterm or finals time, there's not much to study if you've stayed on top of the class since everything is the same. All you need to do is put everything you've learned together, so that it makes sense. Then your mind has a good mental image of all the information, how they relate, and poof, not much cramming, memorization required.
Of course, that's the optimal study method, and very few do that.
