Hi rdrdrd1201,
While GMAT skills can 'fade' over time, it's not clear how long it's been since you were consistently working on your SC skills. In addition, a variety of different factors can impact your performance on any given day, including how well-rested you are, whether you're distracted during your study time or not, the type of material you are using, etc. SCs in particular require a strong attention to detail - beyond knowing the necessary Grammar/Idiom rules, you also need to spot when they apply (and "700-level" prompts can sometimes involve rare versions of standard rules).
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? How many hours do you typically study each week?
2) What study materials have you used so far? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate 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:
4) What is your overall goal score?
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,
