What's on the exam? Any area that we've touched on directly or in indirectly on the assignments, through PS #7. A great way to study would be to do as many of the problems in the textbook as you can for chapters 3 and 4. Additionally, realize that the texbook doesn't have any problems in it on error correcting codes, so don't miss that topic: I'm including anything we did in class on that through last Friday. You can bring an 8.5 x 11 sheet of paper with anything you want on it, on both sides.
