My friend who went to USC swears by the LG Bible. I don't know what to do about Reading Comprehension, but with Logical Reasoning, I feel I can score well because I took a basic logic class in college and can easily identify conclusions, premises, and fallacies. Perhaps you should google these on the Internet and see if that helps you. I also notice I do a lot better when I read the question stems first and then the argument. But anyway, I don't know anything about Kaplan, but I know Princeton Review's online self-paced lessons have helped me a lot. You probably don't have more money to spend, but it costs about 800 bucks and it gives you three months to do a bunch of lessons. They also send you five books, including a book of preptests. The other books have a lot of practice. I am scoring 161 and I really haven't had enough time to put more than a few hours a week of study excluding weekly preptests into the course. I never took a cold diagnostic exam without any prior study, but I'd guess I was scoring a 153. After doing some lessons, I took my first preptest, which was a 157. I hope to keep going up but I still need a lot of improvement on logic games and reading comprehension. However, I have found that practice with logic games definitely helps. I have also found that if I practice a good amount of logical reasioning questions the day before my practice test, I do a lot better. It's like a sport, if you practice all of the skills you will of course improve substantially over time, but if one week you concentrate on one skillset for that sport, you will improve in that skillset, but may go down a bit in the other skills that you haven't practice that week because you're not fresh. So, I recommend doing a bit of practice in each and thinking about what you're doing wrong in each by the answers you're getting wrong. Again, if you can afford a new prepcourse, I would look into Princeton Review's LSAT lessons that are self-paced and online because I think they're quite good.
