Mr. Stanley is a truly outstanding ACT/SAT prep coach. With his efficient writing and reading techniques, I have been able to gradually improve my times as well as answer quality. His son, Costan, is also very helpful and informative math tutor. In fact, Costan may have taught me more than my math teacher at school has. The way that Costan distributes the material is very simple and easy to understand. He thourougly breaks the material down to the point where it is nearly impossible to not understand. Altogether, my experience with both Mr. Stanley and Costan has been a great one that has helped me find tremendous improvement.
