GMAT Question Patterns: Absolute Value
We reviewed questions from the GMAT Prep Tests and Official Guides to identify the most common absolute value patterns that appear on the exam.
This guide is focused on the different types of absolute value problems you may encounter on test day. The goal of this project is to uncover as many recurring question types as possible, for three key reasons:
Most GMAT absolute value problems now appear in the Problem Solving section. In the GMAT Focus Edition, Data Sufficiency no longer includes pure algebraic questions, as these have been removed from the syllabus. For details, refer to GMAT Syllabus for Focus Edition. That said, absolute value concepts may still show up in math-related Data Insights sections, such as Two-Part Analysis. For instance, check this question.
Both number plugging and algebraic methods remain effective strategies. On average, you can expect about 2–3 absolute value questions per test, based on GMAT Prep CATs.

This guide is focused on the different types of absolute value problems you may encounter on test day. The goal of this project is to uncover as many recurring question types as possible, for three key reasons:
- Get a higher score – Master each pattern so you don’t miss out on easy points.
- Save time – No need to do hundreds of questions; just a few from each pattern will do.
- Peace of mind – Be confident that you've covered all known question types.

Hi there,
can I just ask you - are there any other threads for GMAT Patterns beside Arithmetic, Absolute value and Reminders? I found them extremely helpful, but cannot find any other topic covered. Thank you for your answer
