Hi loiszhang,
While the most realistic CATs available are the 6 from GMAC, retaking a CAT that you've already taken is NOT a realistic way to assess your skills - since you will likely see some 'repeat' questions that you have already faced. Unfortunately, seeing even a couple of repeats can 'throw off' the Scoring Algorithm and impact your pacing, energy levels, fatigue, etc. (meaning that they would likely all appear to be better than they actually are). As such, we cannot assume that that 700 score is realistic. Based on your other CAT Scores, it's likely that your current 'ability level' is in the mid-500s to high-500s. It's worth noting that the CATs from Kaplan,
MGMAT and Veritas are all 'close enough' to the real thing that they will provide you with a relatively realistic score assessment (assuming that you correctly take the CAT in a realistic fashion) - so you can use any NEW CATs from any of those sources next.
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 many hours do you typically study each week?
2) What study materials have you used so far?
Goals:
3) When are you planning to take the GMAT?
4) When are you planning to apply to Business School and what Schools are you planning to apply to?
