Hi HariharanIyeer0,
To start, there's a significant difference between doing random questions out of a book and facing a full, adaptive practice CAT in one sitting. In addition, you should be spending closer to 1 minute on a typical SC (NOT 2 minutes). If you typically spend 1.5 to 2 minutes on an SC, then THAT is a problem that would significantly impact your overall pacing and ability to score at a high level in the Verbal section. Based on what you have described so far, it's possible that "your way" of approaching GMAT prompts is the "long way" - and to score significantly higher, you will have to change the way you "see" (and respond to) this Test.
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) What study materials have you used so far?
2) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)?
Goals:
3) What is your goal score?
4) When are you planning to take the GMAT?
5) When are you planning to apply to Business School?
6) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
