Hi Harsh,
Considering the 'swings' in the Quant and Verbal Scaled Scores on your two Official GMATs, at this point you might want to take your practice CATs LESS frequently than once a week. 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 put in the necessary practice and repetitions. The CAT will show you whether your studies are helping you to improve or not.
Before we discuss how best for you to improve, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long did you study before each attempt at the GMAT?
2) What study materials did you use for each attempt?
3) How have you scored on each of your CATs (including the Quant and Verbal Scaled Scores)?
Goals:
4) What is your goal score?
5) When are you planning to retake the GMAT?
6) When are you planning to apply to Business School?
7) What Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
