How Does The Gmat 655+ Score Or +70 Point Increase Guarantee Work?

The guarantee is limited to first-time Manhattan Prep students enrolled in a Private Tutoring Package or our 655+ GMAT Course.
If your baseline exam score is 585+, we will guarantee a minimum score of 655 on the actual GMAT exam (provided you complete “the recommended work”).
If your baseline exam is under 585, we will guarantee a 70+ point score improvement on the actual GMAT (e.g., starting with a 575, you would be guaranteed a 645 or higher) (provided you complete “the recommended work”).
Within 60 days of your last class or tutoring session, you must take the official GMAT exam.
Within 30 days of taking the official GMAT exam, you must submit to us your official GMAT results and your practice test results. Please submit results for all sittings of both the official GMATexam and the official practice tests.

What Do We Mean by the Recommended Work?

Tutoring: You must enroll in the bundled Live Online GMAT Live course to complement your tutoring hours.
You must submit a baseline (starting) practice test score by the first tutoring or class session, whichever comes first. This can be an official test or an official practice test. Take this "baseline" exam under official test conditions. This test must be taken within the 6 months before your course/tutoring starts. If you have testing accommodations approved by GMAC, you may complete all practice tests under those conditions.
Before your first class or tutoring session (whichever comes first), complete the Basic Math Diagnostic exam found in your primary study plan. If your percentage correct is below 80%, you will also need to complete the Foundations of Math (FoM) study plan during the first third of your class or tutoring sessions. This requirement is in addition to completing the assignments in your primary study plan.
You must complete five full-length official practice exams under test conditions as and when assigned in your study plan.
You must complete the full post-test analysis for each practice test, using the template we provide.
You must use all of your tutoring hours over a minimum period of 60 days from the first tutoring session to the last tutoring session.
You must complete all homework as and when assigned in your study plan. Before-class assignments must be completed before that class session takes place. Mark your tasks complete in the study plan as you finish them.
You must attend all class sessions of your course.
You must complete the following in addition to the above:
● All 9 GMAT Live class sessions included in the Private Tutoring package and any assigned before- or after-class homework assignments

Didn’t Score a 655+ or Increase Your Baseline by +70 points?

If you complete the program and put in the recommended work, take the official test, and your score on test day is not a 655+ OR +70 points higher depending on your baseline exam, you have one of two options:

Free re-enrollment: you can contact Manhattan Prep within 60 days of your Manhattan Prep program expiration date and ask to continue your studies and we’ll re-enroll you in a repeat of your original enrollment, completely free.
Money back: you can request your money back.

Important: The guarantee can be used only once for a particular test.

Note: If you choose free re-enrollment and you need more time after that, you can extend your access by purchasing more time.
