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 diagnostic exam inside the course to establish your baseline before you access any other classes or practice problems.
In order to qualify for the guarantee, you must:
- Finish all six (6) Knewton GMAT practice tests (CATs)
- Watch all thirteen (13) on-demand class sessions
- Finish 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.

- How does the guarantee work?
- Simple. If you do the work and don’t gain at least 50 points on your score, we’ll refund 100% of your course fee. We’ll ask for a copy of your official score report, which we’ll compare to your previous score (if you have one) or your first Knewton CAT.
- How do on-demand classes work?
- All past classes are accessible from our on-demand archive. It’s a great resource for catching up on missed classes or checking out a lessons from different teachers. Plus, on-demand sessions are valid forms of attendance toward the money-back guarantee.
- What classes are required? What are optional?
- The 13 required GMAT sessions (3 hours each) in On Demand are available in high-definition, on-demand viewing, so you can make progress as fast as you want. We’ll see that you’ve finished your core work no matter when you view each session.
- Do I need books? Does it come with any books?
- Nope. All the classes and practice problems are online, which enables us to track your progress and make smart, targeted recommendations for what you should work on next. The course includes a clickable, searchable reference catalog that includes concept overviews, videos, and strategies for high scorers. It’s like an online book, but better.
- Is Knewton a new company?
- Knewton was founded in 2008, but our CEO, Jose Ferreira, has a long history with test prep: he is the only person ever to have developed test prep strategies so effective that Education Testing Services (ETS) was forced to remove an entire question type from an exam, admitting that he “broke the code.” He founded Knewton because he realized that computers and the internet could make learning much more personal and affordable through adaptive learning; we built our own platform from the ground up. Other companies still use older, linear methods of teaching.
