Hi QQRamanQQ,
While working through practice questions and Quizzes is an essential part of the overall GMAT training process, the only practical way to assess your current 'ability level' is to take a FULL-LENGTH CAT under realistic testing conditions that match-up with what you will face when you take the Official GMAT (re: take the FULL CAT - with the Essay and IR sections, in the same section order as you'll take the GMAT, at the same time of day as when you'll take the Official GMAT, etc.). Based on THAT data, we can define what you should be working on - and put together an appropriate time-table and Study Plan.
While the most realistic CATs available are the 6 from GMAC, retaking a CAT that you've already taken is NOT a realistic way to assess your skills - since you will likely see some 'repeat' questions that you have already faced. Unfortunately, seeing even a couple of repeats can 'throw off' the Scoring Algorithm and impact your pacing, energy levels, fatigue, etc. (meaning that they would likely all appear to be better than they actually are). Thankfully, the CATs from Kaplan,
MGMAT and Veritas are all 'close enough' to the real thing that they will provide you with a relatively realistic score assessment (assuming that you correctly take the CAT in a realistic fashion) - so you can use any NEW CATs from any of those sources next.
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:
1) How long have you studied in total? How many hours do you typically study each week?
2) What study materials have you used so far?
3) 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)?
4) 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,
