“I have been going to RSM-MetroWest in Framingham for eight years now, and I have loved every year of it. Going to RSM has helped me excel in school, and develop my love for mathematics. The classes not only support the school curriculum but also go beyond it by challenging students with more advanced problems. I love the challenge, and I believe it has only made my interest in mathematics grow stronger. I am truly grateful for the knowledge and skills that it has given me, and I would not be where I am now if it weren’t for RSM-MetroWest.”

– Prakalya Chandrasekar, 10th grader at the Advanced Math & Science Academy

I enjoy advanced math because I am learning about new methods. One of my favorites is the mushroom. With that, you can find the LCM. I like my teacher, Mrs. Alla Farizon. She is very nice and she makes sure you understand the topic. I also like friends in the class. They are fun to play with at break. At my regular school, in my math class, there are a lot of kids who complain about math. But here no one complains about it, so it is much nicer. Every student is excited to learn and the best part is….. it’s math!

– Student, level 5

My son had a wonderful experience at RSM, Framingham, his mathskills improved considerably and was challenged enough to participate in competitions!! Needless to say his school math became very easy for him.

- Vishruta Parikh, August 2018

My favorite thing about advanced math is learning new things. I get new problems to solve. My teacher, Mr. Gene (Sigalovsky) is fun. He explains how to do a method to solve the problem. My teacher is very nice and he is also very fun

- Student, level 3.

I want to take this opportunity to thank you Anna, and the School of Mathematics, for broadening our son's field of vision on mathematics. He has seen many topics and ways to approach them that he would not have had access to otherwise.

- Dar and Einat Efroni, parents of a high school student, 2015

Our son has been with RSM-MetroWest for several years. At the end of the 7th grade he took the Math SAT and earned a perfect score of 800. We just wanted to thank Russian Math for preparing him so well.
