To reiterate previous posters: Do not do anything to prepare. Prep course are worthless. Ignore what other people are doing. Try to figure out, once you start school, what works best for you. Typically, people will brief cases for the first couple weeks/months and then quit. I stopped after a week or two--but some people continue to do it into 3L because it helps them in class and for outlining. I, however, am a believer that case briefs may be valuable at the beginning because they help you understand important information; i.e., if you spend to much time on them, you won't have enough time to do other subjects. But, after about a week or two, they became worthless to me.
