Also, blind review. You need to blind review. Basically do the questions, and then check your answers before actually looking at the right answer choices. Make sure you are 100% sure why each wrong answer is wrong and why each right answer is right. BR is also invaluable IMO.
Blind Review IMO is very important in your LSAT prep. If you can learn why you got any question wrong you can apply that knowledge to other questions later and learn from your mistakes. Without BR you can get lucky guessing questions right but there's no guarantee you'll be lucky on test day. Different books and different methods work better for different people. I looked through the trainer book and thought it had some very good material in it but due to the time span I'm going with the LSAT blog 3 month study plan plus I purchased the Cambridge packets as well as prep tests.
