Hi Hasnain,
This 2nd CAT result implies that the work that you've been doing in the Verbal section has helped you to improve. That having been said, raising a 590 to a 730+ will likely require at least another 3 months of consistent, guided study - and you'll have to make significant improvements to how you handle BOTH the Quant and Verbal sections. You've now scored Q44 on both of your CATs, so you will still have to put some specific work into Quant studies. Thankfully, the GMAT is a consistent, predictable Exam, so you CAN train to score at a higher level. You will probably need more time than you have allotted though, so you might need to push back your planned November Test Date.
Now that you have this recent CAT result, some analysis is in order. Right now, you should NOT be working on "hard" questions - you're losing points in too many other areas. "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'). As such, I'd like to know a bit more about this CAT. 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,
