Hey,
Well, I used Princeton Review, the Hyperlearning books. When I took my practice test, I alway did consistently bad on the verbal, I usually ended up with 5's or 6's. Princeton gave ALOT of practice verbal passages, they know that section is perhaps the most troublesome for many. After working hard with the material, I managed to get my score up to a 9 on the real thing. Not the highest, but I was very happy with my score considering how I was doing on the practice tests. I personally recommend Princeton, but I also talked to people who had success with Kaplan. Anywho, good luck!
