It's not very difficult just make sure to keep your grades as high as possible. Study, read, study some more. Once you think you've studied enough read the material again and study one more time. Create study groups and make sure to get all you can out of every book, every class, every bleeding on-line bit of material you can. Push for A's, but tolerate B's, don't tolerate C's. C's mean you're not studying enough. If you really want some good quality info, search for ABAC and give them a call.
