Oh I'm not memorizing a book at all, I'm working through published LSAT questions, so its not anything new that other companies have made up. It's just the questions that the LSAC publishes out. My instructor got a 180 (haha I feel we're showing off with the instructors) kept mentioning to work through the questions, there are certain types of questions that will appear on the exam, so the more you practice them the better you'll get. Of course this doesn't mean that's all I do. He would tell us to work on logical reasoning, logic games and reading comprehension questions daily to get the hang of it. And then go into the practice exams. That's kind of what's been working for me so I'm trying to tackle as much as I can.
