The most important and best thing you can do is actually going to the classes. Plus the classes are interesting. Also, take notes in class. It will help you with the tests. There is a lot of memorization involved and I really suggest studying for the tests at least 2-3 days before the tests unless you're really good at memorizing things fast. Overall it's a pretty easy class to pass if you go to the classes and put in like 2-3 hours studying.
Don't miss classes, they help you absorb the information and give greater detail than solely the slides.
