Hi kj1993,
If you read enough debriefs, you'll almost certainly come across someone who's used each of the possible Verbal study resources on the market - as well as some broad advice that's simplified to a couple of sentences. However, since I assume that your goal is to significantly improve your Verbal Scaled Score, you'll have to do far more than just read a bunch of debriefs - you'll have to focus on developing specific skills for the Verbal section.
Before I can offer you any advice on how to hone those types of skills, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far?
3) On what dates did you take EACH of your CATs and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
