I took the September LSAT and got a 165. This I got from reading through the PS Logic Games Bible (doing about 80% of its problems) and doing three practice tests (scoring somewhere between 160 and 170 on each try). On the real LSAT I got -5 for LG, -4 for LR, -2 for RC, and -5 for LR. This is worse that what I was getting for LR (average -3), but better than what I was getting for LG (average -8). I plan to retake in February and am shooting for mid-170s.
What is the best thing I can do at this point? Keep taking practice tests? Or should I take a class? (Yes, I lack a slight bit of self-discipline, and hence did not practice as much as I should before September...) But what could the test teach me that I do not already know?
