Top Law Schools

I took the LSAT in October 2008 during a rough patch of life and got a 164. I'm planning to take it again this October, and I'm trying to select the best study materials. Most of the points I missed were with the logic games, so I'm going to get the PowerScore Bible for that.

The question is: for arguments I'm missing about 3-4 per section and for reading comp I'm missing about 2 per section. Which materials are best for improving once you have the basic concepts for the section down? Just taking lots and lots of practice tests? What about the Kaplan LSAT 180? Is it useful?

Thanks in advance!

If you have the tests, you have the best, do them over again until you understand everything. Download PDFs and redo them if you have to.
