Hi dkureem,
If you have not taken any CATs/mocks since your initial one, then we have no idea what your current 'ability level' is right now. To make sure that you receive the most accurate assessment on your next CAT, you have to make sure to take it in a realistic fashion that matches-up with what you will face when you take the Official GMAT (take the FULL CAT - with the Essay and IR sections, at the same time of day as when you'll take the Official GMAT, if you will be at a Test Facility, then wear a face mask, etc.). Once you have that Score, you should post back here (or you can feel free to PM me directly) and we can discuss the results and how you might best proceed with your studies.
Going forward, it's worth noting that 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. In addition, the process of taking (and reviewing) a CAT requires a significant amount of energy and effort - and takes time to 'recover' from. This is one of the reasons why you typically shouldn't take more than 1 CAT per week - and your last CAT should be taken about 1 week before Test Day. As such, you really shouldn't take more than 1 FULL CAT per week.
Before I can offer you any additional 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? What “brands” of CATs/mocks have you used?
3) What were your Quant and Verbal Scaled Scores on your 1st CAT?
Goals:
4) Is your overall goal score a 620 or something else?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
