I would not read anything more than they tell you. If it was like mine, it will be very close to like how a typical law school class will be. You will have to pay close attention to the professor's style and what he expects on his exams and papers. For example, if he is very strong on public policy, be sure to mention something about it. Or for example, if he doesn't care about the issue, for example, if the class is on torts, and he just prefers you to write,
A v. B, and then underline battery, then do the format he suggests.
In my summer class, we had a TA. They had very very very much influence as to if you would make it or not. Do not underestimate their power. Mine was so that if you passed the exam but the TA still thought you wouldn't make it, the TA could deny your admission.
