Santhra Thambidurai, Founder of Numeracy Coach
I am an experienced mathematics teacher with experience teaching at a top 2% high school in the United States, having taught many subjects from pre-algebra through AP Statistics/College Statistics, to students in middle school through graduate school. After my first child was born, I decided to continue my passion for teaching in the form of teaching students 1:1 or in a small group and also embrace the flexibility that comes with it. I have logged over 5000 hours of tutoring and have taught students from all over the United States, from schools such as WW-P (top 2%), Palo Alto (top 2%), Princeton (top 5%), Evergreen Valley (top 5%) etc- all prestigious schools from the East to the West coast.
I utilize various technologies to work with students online, from screen-sharing applications to review work and concepts, video chatting to foster relationships and engagement, and note sharing to support reinforcement and review.
My drive to help my students perform better is evident in my AP scores. 92.1% of my students earned a 4 or above on the 2017 AP Statistics Exam compared to 28.8% of all exam takers.
My latest SAT student from Montgomery High School, NJ, had a 240-point increase after 12 classes. A student who I tutored in AP Stat from Hillsborough High School (NJ) had a 76% when he started with me in November. He ended the year with an A and was exempt from his final.
