An example of a question taken from the 1984 Official GMAT guide that is part of the recently released Official GMAT Practice Questions 2. Almost all of the quantitative reasoning questions are from that era.

## Review of GMAT Official Practice Questions 2

- 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.

## GMAT Official Practice Questions 2: May 21 release date

GMAC, the writers of GMAT, will be releasing a new set of practice questions called GMAT Official Practice Questions 2 on 21st of May that includes a set of 350+ questions. This will include questions from Quantitative, Verbal, and Integrated Reasoning and will cost $30.

This product is a sequel to the GMAT Official Practice Questions 1(originally called GMATPrep Question Pack 1) that was released in 2012 and has 200 Quant questions, 180 verbal questions, and 24 Integrated Reasoning questions.

I highly recommend students to use the official GMAT practice questions and this is a welcome addition to an already large inventory of official GMAT practice questions. 10 years ago I used to complain that there weren’t enough official GMAT practice questions that were of high quality. However, today I can say that there is no dearth of good quality official GMAT practice questions. The only downside is that you have to pay for all of these additional products.

## GMAT Problem Solving Question 01: Arithmetico-Geometric series

The following GMAT Problem Solving question tests your understanding of how to find the sum of an arithmetico-geometric series. This is a difficult question and you should expect something along these lines if you are scoring Q49+ on the GMAT quantitative section.

The limiting sum of the infinite series

$$ \dfrac{1}{2} + \dfrac{3}{4} + \dfrac{5}{8} + \dfrac{7}{16} + \dfrac{9}{32} + \ldots $$

whose $n$-th term is $\dfrac{2n-1}{2^n}$ is:

- $\quad \dfrac{5}{2}$
- $\quad 3$
- $\quad \dfrac{7}{2}$
- $\quad \dfrac{15}{4}$
- $\quad 4$
