GMAT Books vs. GMAT Online Preparation Courses– Which is better?


gmat books vs gmat online resources


Here are five reasons why GMAT online courses are better to prepare from than GMAT books:

  1. Less time to consume

If you are preparing from a data-driven online resource, you’ll need 7 hours for every 10-point improvement on the GMAT. Studying from books take 12 hours to do the same. Why? Look at the next point.

  1. Easier to focus

Audio-visual content is four times more interactive and hence effective. It is easier to focus, and therefore you require half as many revisions to reach a higher competency level. The result is that you learn more in less time.

Adam scored a dismal 490 and 530 in his first and second attempts. The reason for his failure – he studied from an old book in his first attempt and again used GMAT books to prepare for his second attempt. For his third attempt, he used e-GMAT’s interactive online preparation resource and scored a 700 on the GMAT.

  1. Online content is more up to date

Online content always keeps updating according to changes and trends. Recently GMAC changed the GMAT format with a reduced number of questions and test duration. To adapt to the change, the online content of GMAT preparation updates within a day or two. However, you cannot expect the same to happen in the case of books. Books will only be updated when reprinted.

  1. GMAT is an online test

Since GMAT is an online test, it is better to train yourself on a computer during your preparation. If you prepare only from books, you’ll have to transition yourself from books to preparing on a computer, which will take up your precious preparation time. In turn, you can use this time to work on your GMAT Ability and Time Management.


Confused about your GMAT strategy? Attend our webinar on GMAT strategy and define your study plan for a high GMAT score.


  1. GMAT is a computer adaptive test

A computer adaptive test adapts itself according to the test taker’s performance. GMAT will throw different difficulty level questions at you during the test. The difficulty level will depend on how well you are doing during the test.

When you prepare using books, you miss this vital part: preparing yourself for the adaptive nature of the GMAT.

GMAT Forums

Forums such as GMATClub, Beat The GMAT, Pagalguy offers a massive amount of free study material. You also get to interact with like-minded people and GMAT experts to help you solve the problem.
