Hi kamrulhasan26043,
It's been almost 3 months since you took the Official GMAT, but it's not clear how you have been studying since then. In a prior post, you noted that your Score Goal is 550+ and that you wanted to score a V30. However, since there are lots of different Scaled Score 'combinations' that will earn you a 550+, you do not necessarily need to score that high in the Verbal section - and you don't have to correctly answer ANY high-level SCs to earn that type of Score (so putting a lot of time and effort into that practicing those types of questions is probably not the best use of your time).
1) Are you interested in applying to a Program that requires Applicants to score at least a V30?
2) How long have you studied in total? How many hours do you typically study each week?
3) What study materials have you used so far?
4) 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)?
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,
