Keep a stack of note cards now, writing down on one side a word, and on the back the definition, for every new word you learn and occasionally flip through it. Second, the LSAT questions are supposed to based on things like Supreme Court Opinions, so spend some of your downtime reading more! Mehran, the founder, believes in reading the Economist, and it truly helped his score, so I also recommend it!
Hope that helps and happy studying,
