Hi melisa1,
Thank you for reaching out, and I’m happy to help! I’m going to provide some general insight into GMAT studying that should answer most of your questions. First of all, I think it is a good idea to take a few days off and then dive back into your prep. Since it sounds as if you have put a lot of time and energy into your studying but have not seen the results you need, you may consider adjusting your study routine. Since you have a decent foundation in verbal and an above average grasp of quant, you do not need to start your studying from scratch.
When determining a new study routine you must remember that what makes the GMAT such a challenging exam is that 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 study in this way?
For example, when studying verbal focus on learning one section at a time: reading comprehension, sentence correction, or critical reasoning. When learning about critical reasoning, for example, you want to learn all aspects of critical reasoning: strengthen and weaken the conclusion, resolve the paradox, find the conclusion, must be true, etc. Follow up your learning with focused critical reasoning practice, so you can determine your specific weaknesses within that topic. You should follow a similar routine for sentence correction and reading comprehension.
For quant, since you are already scoring at a high level, you might consider following a similar but slightly altered approach that consists of more focused practice. For example, if you are reviewing number properties, be sure that you can practice 50 or more questions just from Number Properties: LCM, GCF, units digit patterns, divisibility, remainders, etc. The results of that practice will help you determine your weak areas within that topic. Once you find and fix your weak areas, then move on to the next quant topic.
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 will be 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.
As far as study resources, you may consider using a self-study course rather than a book or class. Self-study courses are typically more robust than GMAT books, and they are more flexible that a GMAT class. If you would like to learn more about what online resources are available, check out the verified course reviews here or on Beat The GMAT. After doing some research you should be able to find a course that is a good fit for you.
Once you feel you have found and fixed your weaknesses, start taking Official MBA.com tests to track your progress. You can start with the
two free exams. After that you can purchase
exam pack 1 and
exam pack 2. At this stage your practice test scores should be more consistent and more reflective of your GMAT score goal. Assuming you take all 6 MBA.com exams, I do not think you need to take any more than those.
