Start improving your score right now.

Improve by at least 50 points or your course is free.

The best guarantee in GMAT prep, hands down

If your score doesn’t improve by at least 50 points, you get a full refund. No hassles, no sneaky fine print. Just your money back. It’s even in our Terms and Conditions. All we ask is that you attend the classes and do the work.

What you’ll need to do

If you’ve taken the GMAT before, then your highest previous GMAT score will serve as your baseline score. If you haven’t taken the GMAT yet, you’ll take a practice GMAT inside the course to establish your baseline before you access any other classes or practice problems.

Our CAT algorithms are overseen by David Kuntz, our head of research, who previously held senior positions at ETS and the LSAC. There he created the first automated test assembly algorithm and system for the current LSAT, the first web-based computer-adaptive test delivery system, the first online AP practice program using real AP graders, and the first large-scale web-based portfolio scoring and management system.

In order to qualify for the guarantee, you must:

- Complete all six (6) Knewton GMAT practice tests (CATs)
- Watch all thirteen (13) on-demand class sessions
- Complete all required homework for each session

How it works

After taking a Knewton GMAT course and taking the GMAT, if you don’t improve by at least 50 points and want to claim a refund, simply send us a copy of your score report. Your score report will contain your most recent score and, if applicable, your previous score as well. We’ll check your course history to make sure you did the required work, and if you qualify, we’ll issue a refund.
