She is patient, encouraging, and inspiring! I took AP Calculus B/C last year and she helped me with the class and AP Exam prep. I got a 5 on the AP Calculus B/C exam! This year, I am taking AP Physics C. She makes even the most difficult concepts seem easy. If you like Physics and Calculus, she will increase your love for the subjects tenfold. If you are looking for an AP Calculus/AP Physics tutor, she MUST be your FIRST CHOICE!

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!
Manonmani T.

She strategically chooses MCQ and FRQ problems to review during sessions, and she makes tricky, abstract word problems predictable and easy. She also knows so many useful tips and shortcuts. I reviewed for my exam with Alexi, and I scored a 5. I HIGHLY recommend Alexi to anyone who wants help with AP Calculus AB. If you are willing to put in the work, she will help you achieve a level of expertise that will be so much more than what you expected. Thank you Alexi :)
