Hi thadmelo,
With a V25, you lost significant points in at least 2 of the 3 major Verbal categories (SC, RC and CR), so if your goal is to score at a much higher level, then you're going to need more than just 'tips' to earn that higher score. You'll need to learn to 'see' (and respond to) the GMAT in new ways. Before I can offer you the specific advice that you’re looking for, 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?
2) What study materials have you used so far?
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores for each)?
Goals:
4) What is your goal score?
5) When are you planning to retake 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,
