In this module, you'll learn all of the concepts, techniques and strategies needed to answer arithmetic questions on the GMAT. In particular, this module covers:

  • Basic operations
  • Signed numbers
  • Decimals
  • Fractions
  • Percents
  • Ratios

Two ways to prepare

Beneath each video lesson in this module, we have a Related Resource box with practice questions that test the concepts covered in the video. With this lesson format, you have two learning options:

  • Watch the video lesson first and then reinforce your learning by answering several related questions, or...
  • Tackle the practice questions first and watch the lesson only if you need help with the concepts the practice questions test

Additional Practice

NOTE: In each of the above video lessons, you’ll find a Related Resources box containing several practice questions that are specifically related to the concepts covered in that lesson (e.g., the lesson on ratios). Conversely, the practice questions below cover a variety of topics under the umbrella of GMAT Arithmetic, and are intended for general reinforcement.

Given this, you may find it beneficial to work on the questions below after you’ve mastered the module content by watching the video lessons and answering concept-specific practice questions from the Related Resources boxes. For more on this learning strategy, visit our course overview page.
