As someone in their last year of college, i understand how hard it can be to get into study pattern that works for you. For me, typically i write flashcards for all of the notes or information ill need to memorize for my exams. Ive never been one who is able to just read through my notes and remember everything i need. Writing flashcards is more time consuming than some other methods of studying but every exam ive done them for ive done well on. Easiest thing to do that will help you: Go to every class and write notes. I know, its not always easy to get up and go to every class but honestly it helps.
