Good to see you posting again PBD!
One thing I learned very fast was that I had to figure out the best way to study, that worked for me. I tutor bio students, and the one problem they all have in common is that they have not figured out what works for them. That's usually the problem in most cases.
For me, I try to read assigned textbook chapters (or at least skim them) before class. Some teachers put up their lecture powerpoint slides; if they do so before class, I skim those too. That way, I can follow along in lecture without getting lost.
When it comes down to studying for exams, I go through my notes while also going through the appropriate part of the textbook. I don't do well in groups, so I try to avoid that. Usually when I study in a group, I come prepared to answer everyone else's questions; it's a good form of review for me. Reviewing past exams is also helpful, but often times, they are different from what your professor will give you for your exams. Therefore, they are good but should not be relied upon too heavily.
Time management is key like fuzzywuz said. Don't fall behind on assigned work/reading. Do a little bit of reading/studying everyday. Then review the next day to make sure you've internalized it. Good luck.
