  • I looked for many tutoring centers for IB curriculum but was not satisfied. Catalyze is a great center where the tutors were very encouraging. My daughter has developed a liking and has built confidence in Math and Physics. Both her tutors Mrs. Vrinda and Mrs. Thahirunnissa have been instrumental in developing her confidence. I have recommended you to many of my friends. It is such a relief not to worry about our daughter's safety when she is learning online. We save time and energy.

  • Vrinda Ma'am taught me higher level AS and A level math as well as IIT-JEE math prep. She is awesome in her knowledge and delivery. She also takes the time to explain in a very simple manner and equip with enough question practice.

  • I had a fear of Math and was not very consistant in my classes with another online service provider. But when I moved to Catalyze the level of teaching and follow up was so encouraging that I lost my fear of math and started enjoying my classes, thanks to Vrinda Ma'am.

  • "Sagarika was into advanced math classes in Catalyze where she appeared for advanced 10th grade math in 9th grade and scored 93%. Vrinda Khemani, her math teacher taught her with great dedication and passion. Very happy that we came to Catalyze and found such a teacher."
