Hi Qazi Shakeeb,
If you are struggling with
OG questions, it may be an indication that you have not fully learned each GMAT math topic prior to practicing those questions. Thus, you might consider first learning each GMAT quant topic prior to doing random practice from the
OG.
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 study in this way?
For example, if you are learning about Number Properties, you should learn as much as possible about that topic: LCM, GCF, units digit patterns, divisibility, remainders, etc. After that, be sure that you practice with 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 truly mastered that topic.
Here’s an article that may help you better understand
how to design a robust GMAT study plan.
Also, you may consider using some more robust prep materials in addition to the
OG. While
the Official Guide is a great book because it has official questions from past GMATs, there are not enough questions given about each topic to provide full exposure to all GMAT topics. Additionally, the questions are presented in a random order, so it’s challenging to use the
OG for focused practice.
Have you considered an online self-study course? In comparison to GMAT prep books, self-study courses typically provide detailed study plans and have granular analytics, so you can easily track your progress as you move through the course. By being able to track your progress, you will remain more engaged, and you’ll be able to more accurately forecast when you are ready to take your real GMAT. If you would like to learn more about which online resources are available, check out the verified course reviews here or on Beat The GMAT.
