Hi Suryangshu,
Your question focuses on one specific approach to one type of question in one category in the Verbal section - and that's a remarkably specific issue. As such, I'd like to know a bit more about how you've been approaching your overall studies, as well as your timeline and goals:
Studies:
1) How long have you studied?
2) What materials have you used?
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)?
Goals:
4) What is your 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,
