I cannot brag enough about Ms. Sarin. She has been helping my son with Precalculus and now AP Calculus. My son also attended her SAT prep and he just scored 1550+ on first attempt. His AP Calculus grades are all above 90 and he was struggling to get a B in Precalculus. She is not just any tutor. She is a counselor, advisor, and also a friend. She genuinely works for child’s best interest and not money. My son’s confidence level is going higher and higher. “

Ms. Sarin is able to teach complex concepts in a clear and understandable way. She is patient, thorough, and extremely diligent. There was one instance where my daughter told me that while her teacher at school taught a concept in a confusing seven-step process, Ms. Sarin was able to break it down into three simple, clear steps. She is an excellent teacher, cares about each student, and seeks to meet each student at his/her level. She is highly recommended!

Abby Sarin has been an excellent tutor for both my children. Abby plans the sessions meticulously and is very focused on how she wants to approach each lesson. My daughter has improved in KAP Geometry since being tutored by Abby. My son improved so much to where he doesn’t need to come as often. Abby is very knowledgeable, honest, and professional and my daughter finds her approachable and has really enjoyed being tutored by Abby. I am assured that my daughter is receiving the support that she needs as she has improved in her class. "
