My daughter completed the 6 week course, and we paid 699.00. It was with a guarantee that she score in the 99th percentile. No tutor showed up on the 1st day of class, so they had to reschedule to a different date. This date caused her to miss work, thus out more money. She did improve, but did not score in the 99th percentile. When I called to get a refund, they advised that I was outside my 30 day window to do so, so no refund would be given. They can inconvenience you and cause you to lose money to re-schedule when their moderator does not show up, but they are exact on the 30 day window, and that is even with documents t hat have to be snail mailed. GO WITH OTHER COMPANIES, same results but better reviews.
