OG 2020 & OG 13th Edition + Weak in Quant

Hi RafZaf,

If you have gotten 'stuck' at a particular 'Score level', then continuing to work through 100s of practice questions in the same ways that you did before might not lead to a significant improvement (especially if you have developed any 'bad habits' that you are not directly working to fix).

The GMAT2021 is almost identical to the GMAT2020, so there's not much benefit to working through both of those books. However, with each prior version of the OG, approximately 10% - 15% of the questions were swapped-out. By extension, an older book (such as the OG13) would likely include 100s of questions that you have not seen before. If you were looking for a bunch of 'new' Official questions to work through, then purchasing that book would be a reasonable idea. Again though - if your goal is to score significantly higher than you are currently scoring, then your focus has to be on learning and practicing the proper Tactics.

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:

Studies:
1) How long have you studied in total? What study routine do you typically follow each week?
2) On what 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)?

Goals:
3) What is your overall goal score?
4) When are you planning to apply to Business School and what Schools are you planning to apply to?
