Network with them to find out who took the professors you are currently taking. Ask them questions on how they dealt with the professor's exams and what tips they might have to share. Don't be intimidated about asking these people questions. After all, they are only a year away from where you currently are. Furthermore, they probably want to help.
People usually become lawyers partly because they want to counsel people.
Your questions feed that need. Most law schools also run an academic support program where 2Ls and 3Ls tutor first year students in studying skills. Although the course is only as good as the instructor, I urge you to attend these sessions to pick up on skills in exam writing. Course like these are often very good to get at the idiosyncrasies of a particular professor. Practice Exams and Model Answers Don't wait until the end of the semester to look at practice exams.
