Unlike most tutoring services, we have a 100% satisfaction guarantee. If you are not satisfied with our services, then you do not have to pay. Of course, if you simply want to try another tutor, then you will be required to pay the tutor at the end of the session as a customer usually would. Also, we ask that if the session is not going well, then you stop it before the end. These stipulations are only to prevent abuse of our guarantee.
