Hi in4192,
The scoring algorithm on the Official GMAT is far more complicated than most people realize. It takes into account a number of different factors - far more than simply the number of correct answers - so you shouldn't be spending your time trying to figure it all out. You'd be better served working on building up your overall Test-taking skills.
Before I can offer you any advice for your studies, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied? How many hours do you typically study each week?
2) What study materials have you used so far?
3) Are these the only two practice CATs/mocks you have taken? 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)?
Goals:
4) What is your overall goal score?
5) When are you planning to take 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,
