Hi Arvind,
I realize that you are just beginning your GMAT prep; however, the results of a practice GMAT will provide a baseline score and give you the valuable information you need to determine how far away you are from your goal score. If you want to do some basic refreshing, that’s fine, but soon thereafter you may consider taking a free
MBA.com practice exam.
I also welcome you to take my free
37-question quant diagnostic. After completing the diagnostic, you’ll be provided with a detailed analysis of your proficiency level on GMAT quant topics as well as an opportunity to discuss your diagnostic results and GMAT plan with me or another TTP instructor/coach.
In regard to how to study for the exam, you must remember that 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.
For example, if you are learning about Number Properties you want to make sure you learn everything possible about that topic: LCM, GCF, prime factors, divisibility, remainders, etc. After that, be sure to practice a lot of questions (50 or more) just on Number Properties. The results of that practice will help you to determine how well you have mastered that topic. Although this is just one example, you would want to follow this process for all sections tested on the GMAT. With that said, you may find it more helpful to study quant and verbal in the same week, rather than studying quant one week and verbal the next. For instance, if you are studying 20 hours a week, break up the week into 10 hours for quant prep and 10 for verbal.
If you find that the books you are using do not provide for this type of focused learning and practice you may consider some more robust study material(s), such as an online self-study course.
