If you can't find anyone to study with, try to meet at the school a few days before tests. Even a couple of hours before the exam can help nail down one or two difficult concepts. If that doesn't work - go to barristerbooks.com and buy the tapes. They won't help you study the actual material that you are taught in class, but they are very good for the concepts. Very good to have if you spend a lot of time in the car.
