Assuming you took good notes, best thing to do is study them ASAP and as much as possible. Even if you think you memorized the entire thing, keep studying. Also, if you really need help, ask one of your class buddies to help you study. Dont forget to thank them after and dont pick ones that are in the same position as you =P.
