I have been out of school for a couple years and now I am back in. In the past I got mostly B grades but I am looking to get only A grades now. Now that I'm starting all of those science classes, they are killing me! My Bio instuctor says our first exam is going to be a "bloodbath" and I believe him because because he makes all of the quizzes hard. Tell me... what kind of things did you do to recieve an A and what little hints do you have to make me a better student...
