After just one session with Bill, my son is much less stressed going into his **AP** **Calculus** test today. Even with incredibly difficult subject matter, Christopher seems less stressed and better prepared. My son was able to get an A in **AP** **Calculus** BC and a 5 in the **AP** **Calculus** BC exam! Thank you, Bill, for your help!

She has a great sense of humor, and taught my son many useful calculus techniques in only an hour. Not only that, as his school doesn't offer **AP** **Calculus** BC, she offered to help him with that portion in order for him to take the **AP** **Calculus** BC exam rather than the AB. Needless to say, we have made the decision to use Margery on a regular basis, especially as Calculus can be a rather daunting class to teach oneself and she made it an enjoyable learning experience for my son.

Andrew was great. I am a senior in high school taking **AP** **Calculus**. Andrew was knowledgeable about the content I needed to cover and was very helpful. I would definitely recommend to anyone in **AP** **Calculus**.
