Review of GMAT Official Practice Questions 2

Leave a Comment

 

  • GMAT Official Practice Questions 2 has been released by GMAC on 21st May 2021 and costs $\$30$.

  • GMAT Official Practice Questions 2 consists of 406 practice questions (199 quantitative and 207 verbal reasoning). There are no Integrated Reasoning questions included with this product.

  • There are 101 Problem Solving questions (32 Easy, 35 Medium, and 34 Hard).

  • There are 98 Data Sufficiency questions (36 Easy, 35 Medium, and 27 Hard).

  • Most of these questions, and I would say nearly all of them, are taken from old official GMAT paper tests from 1990s and before. I haven’t seen any question that looks like it was administered in the last five years on an official GMAT test. Of course, you have to realize that I can’t be exhaustive about my claim because a lot of it is based on memory.

  • The downside of the older GMAT official questions from the paper tests is that the average time per questions was about 1.5 minutes, which means the questions will appear to be easier than what is on the current exam. However, keep in mind that even in the latest 2021 GMAT official guides there are many questions that are from those same old GMAT paper tests.

  • My personal recommendation would be that you spend your $30 on the GMAT Official Practice Questions 1 product, which has questions that are closer to the current difficulty level of the GMAT.

  • This product would be suitable for students who are scoring average on the quantitative section and need additional practice with medium level difficulty questions.
