Hi nkme2007,
The Verbal section of the GMAT is as consistent and predictable as the Quant section is, but Verbal questions have no 'safety net' (meaning that if you make a little mistake, you won't realize it - you will just convince yourself that one of the wrong answers is correct). As such, you have to do really precise work on each Verbal question that you face. SCs are typically based on 2-4 grammar rules each (and you don't necessarily need to know all of the rules to select the correct answer). In that way, SCs are 'technical' in nature (similar to how Geometry questions require knowledge of formulas), so you need to know the necessary grammar/idiom rules (and when they apply) to score higher in this category.
You list an Official Score in your profile that includes a V22. How long ago did you earn that Score? Beyond that, 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 in total? How many hours do you typically study each week?
2) On what dates did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
3) What is your overall goal score?
4) When are you planning to retake the GMAT?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
