Hi JognDoe101,
Unfortunately, there is no practical way to use your results from a mini-quiz to estimate how you might perform on the Official GMAT. If you would like that type of assessment, then you will have to take a FULL-LENGTH CAT under realistic conditions. From your post, it is not clear whether you have taken any CATs yet or not. 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:
Studies:
1) How long have you studied?
2) What study materials have you used so far?
3) How have you scored on EACH of your CATs/mocks (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your 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,
