Hi intlawgrrl,
To start, while the
OG books are great sources for practice questions, they're not designed to teach you Tactics, patterns or the little 'secrets' behind the GMAT - for those, you'll need Course-oriented materials. The recent versions of the main
OG (the GMAT2022, GMAT2021 and GMAT2020 books) are all remarkably similar to one another - so if you are looking for LOTS of additional
OG questions to practice with out of a book, then you would need to go back to an older version of the
OG (such as the GMAT2016 or GMAT2017).
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? How many hours do you typically study each week?
2) What study materials have you used so far? What “brands” of CATs/mocks have you used?
3) On what dates (or approximate 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:
4) What is your overall goal score?
5) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
