Hi piyushbadola,
Depending on when - in August - you plan to take the GMAT, you could have another 6-10 weeks of potential study time. While you could potentially improve a great deal in that timeframe, these 2 Official Scores show that you continue to "see" (and respond to) the Verbal section in the same general ways. From what you describe, your studies have revolved primarily around working through lots of practice questions, but you have not spent much time (if any) learning the Tactics, patterns or little 'secrets' of the Verbal section.
There are Verbal-specific study materials that I can recommend that you try. Before we discuss those options though, I'd like to know a bit more about your last CAT. "Review" is an exceptionally important part of the GMAT training process; your ability to define WHY you're getting questions wrong is essential to defining the areas that you need to work on (and the specific things that you need to 'fix'). While a full Mistake Tracker would provide a lot more information, there are some basic questions that you should be able to answer (and the more EXACT you can be with your answers, the better):
After reviewing each section of this recent CAT, how many questions did you get wrong....
1) Because of a silly/little mistake?
2) Because there was some math/verbal that you just could not remember how to do?
3) Because the question was too hard?
4) Because you were low on time and had to guess?
5) How many Verbal questions did you 'narrow down to 2 choices' but still get wrong?
GMAT assassins aren't born, they're made,
