None of the reputable GMAT-Prep insti's outside of India make such a claim. And some of them are far superior to those in India. Let me guess the terms and conditions for the offer made to you
1. Insanely high-fees
2. You have to promise to do ALL of the assigned work --- Assignments, ClassTests, take-home, attend all classes, Mocks
3. You will also have to take a test first before you are eligible for this guarantee. Depending on your performance, they will give you the guarantee.
Stay a mile away from these places.
I am looking out for a GMAT PRIVATE TUTOR.
I have also got calls from institutes that promise 750 score. If I don't get the score they will refund it. They would give a written agreement.
Are they genuine.
Pls answer my doubts.
Frenz kindly help me to find gmat tutor
