Hi Prateekj05,
In your first message, you stated that you "don't have much time"; does that mean that your Official Test Date is coming up relatively soon? If you're thinking about taking lots of CATs in a short period of time, then you should know that that is NOT a good idea.
While there are certain aspects to Test Day that you can really only learn by taking realistic, FULL-LENGTH CATs, once you've learned those things, it's important to remember that taking lots of CATs will NOT make you a better Test Taker. A CAT is really a 'measuring device' - when used correctly, it will give you a realistic score and help define your strengths and weaknesses, but it will NOT help you to fix any of those weaknesses. To raise your scores, you have to learn the necessary Tactics and put in the proper practice and repetitions. The CAT will show you whether your studies are helping you to improve or not. As such, you really should not take more than 1 FULL CAT per week and your last CAT should be about 1 week before Test Day.
1) How have you scored on EACH of your CATs (including the Quant and Verbal Scaled Scores for EACH)?
2) What is your goal score?
3) When are you planning to take the GMAT?
GMAT assassins aren't born, they're made,
