A friend of mine took a speed reading course at a local junior college. He felt that it helped him tremendously. He didn't grow up speaking english and certainly never read much as a kid. I, on the other hand, read a lot, and I think that was the key to my success. I practiced for the verbal section a couple of ways. One, I did tons of practice tests, all those that I could get my hands on, and I always did them in a timed environment, just like the real thing. I also tried to read a lot, something I do normally. Don't read easy stuff, though, and when you are reading, even if it's for enjoyment, conciously try to read as fast as possible. That's all I can say...there are no easy tricks, only hard work and practice.
Good luck,
Adam
