I would say honestly pay attention and if you don't understand any concept then make sure to ask questions about it until you understand. VOCAB is very important so make sure you memorize all of them before the exam. There are a lot of quizlets that will prepare you for his tests but makes sure you understand what is going on. Do your notes at a good pace and don't wait to do them the night before. It is an easy class if you pay attention and complete your work on time.
