# Free 25-min SAT Math diagnosis with Tan

> See if you qualify for the 750 Guarantee. We'll work through a few real SAT questions together so I can see how you think and find exactly where your points are going. No prep needed. If you qualify, I'll tell you your target, how many hours it takes, and the price ($69 an hour). Calls can run a few minutes over, so leave a little space after.
