### My review of 2021 GMAT Official Guide Quantitative Review

1) GMAT Official Guide Quantitative Review 2021 has been released in ebook format and can be purchased from: https://www.efficientlearning.com/gmat/

2) The physical copy of the GMAT Official Guide Quantitative Review 2021 will be available on Amazon and other retailers starting 3rd June 2020.

3)This year's guide is a significant improvement over previous editions. Instead of replacing questions, as has been done in the past, this year the test writers added a new set of 54 questions to last year's total of 319 questions in the 2020 GMAT Quantitative Review guide.

4)The new guide has a total of 373 quantitative reasoning questions: 212 are Problem Solving questions and 161 are Data Sufficiency questions.

5) A total of 54 questions are new to the 2021 edition of the GMAT Quantitative Review.

6) Here is the list of the 36 newly added Problem Solving questions: 37, 55, 59, 73, 80, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 135, 147, 150, 156, 157, 158, 161, 163, 179, 204, 205, 207, 208, 209, 210, 212.

7) Here is the list of the 18 newly added Data Sufficiency questions: 214, 216, 218, 221, 224, 234, 241, 248, 249, 264, 265, 271, 272, 273, 276, 277, 307, 370.

8) There are quite a few difficult questions in this year's GMAT Quantitative Review guide. I would rate at least 10 of them to be on the very difficult side, and more so when you have to do these problems under time and pressure.

Cheers, Dabral

Hi-
Just getting started on my prep journey and haven't bought any materials yet.
Do you think the changes are significant enough to warrant buying the 2021 OG over a used 2020 version? I also intend to purchase the Manhattan Prep books that come with access to their online content.

Thanks!
