Doing the homework. The best way for me to get any high grades is to do homework. And to try to do it within the week of the exam because I end up forgetting everything. Practice, practice, practice! (I'm an accounting major so this worked for those types of courses and mathematical courses. For my English classes I just make sure to read what's assigned. That usually works just fine.)
Oh! And I always pop gum into my mouth 5 minutes before an exam. I heard that chewing on something gets the blood-flow to your brain pumping or SOMETHING along those lines... It actually works for me so why not?
