My college days started in the early 90's, so it's been a long time, and I'm not a biochemist, but I have a tip to share with you, and anyone else who is about to embark on the college journey: Learn memory techniques, if you haven't already. There are various sources on the subject. I like learning by reading. One easy book on the subject is Unlimited Memory: How to Use Advanced Learning Strategies to Learn Faster, Remember More and be More Productive
