Hi KuanyshGmat,
The scoring algorithm on the Official GMAT is far more complicated than most people realize - and it takes into account far more than just the number of correct answers. Since that algorithm is proprietary, no GMAT company has an exact match for it, thus CAT scores can vary a bit based on the 'biases' involved in their respective designs. The most realistic CATs available are the 6 from GMAC (the 2 free CATs, and each of the 2 that come with Exam Pack 1 and Exam Pack 2), so if you have not taken any of those CATs yet, then you should plan to take one of them next. You could potentially end up with a 610 based on the number of correct answers that you noted in your post - but you could also score potentially notably lower.
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:
1) What type of study routine have you been following since August? How many hours do you typically study each week?
2) You started off your studies with a few books. Have you added any additional study materials over the last 3 months?
3) Have you taken any other CATs/mocks besides this one? On what dates (or approximate 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)?
4) Are you thinking about applying to Business School this cycle? If so, then what specific application deadlines are you facing?
GMAT assassins aren't born, they're made,
