Hi Bzo,
I agree that it could be a good idea to take a full CAT this weekend to get an up-to-date GMAT score. You may consider taking an Official MBA.com exam, as these exams provides the most accurate exam experience and use the most accurate scoring algorithm.
In the meantime, to help diagnose your GMAT quant strengths and weaknesses, I welcome you to take my free
37-question quant diagnostic . After completing the diagnostic, you are provided with a detailed analysis of your proficiency level of all GMAT quant topics as well as an opportunity to discuss your diagnostic results with me or another TTP instructor/coach.
Finally, if you find that your quant is not improving despite many hours of prep, you might consider adjusting your study routine. Remember, the GMAT is such a challenging exam because there are relatively few questions asked in a given exam, yet those questions come from a huge topic pool. Thus, the best way to get a great GMAT score is to have a thorough understanding of all the topics that may be tested on the exam. To develop such mastery, you want to strive for linear and targeted learning and follow that with focused practice. In other words, you want to master one topic before you move to the next. Have you been able to do this?
Once you take your official CAT, report back with the score breakdown, and we can provide some further advice.
