If the foundation is not good, you'd better go to Wendeng's cram school, but you should also pay attention to the methods, because Wendeng's cram school is basically taking notes. You should listen carefully instead of taking notes all the time, because many people always take notes. You can copy other people's notes and listen as carefully as you do in class, which will be very effective. Buy another review book and do it well. I'm sure there will be no problem.
