What helped me improve my score 8-9 points was using the magoosh verbal flash cards. I memorized as many of the words as possible and that helped me significantly.

I highly recommend magoosh to improve both your verbal and math scores. I raised my verbal score by 7 points and my math by 8 points in 3 weeks of studying using only magoosh.
I signed up on their website, costs about 100 dollars, and I used their free vocab app as well. I focused more on the videos they supply you with and did not memorize much vocab at all. Also took a ton of practice tests, probably once every 2-3 days to keep track of my progress.
Thanks for the advice! I already memorized 700 words from magoosh out of the 1,000. I just didn't memorize/study the advanced words which I probably will start soon.
