Suman Saurav Thakur

Chandigarh University

Biography

I have done my mechanical engineering and then Marine Engineering. After a brief sea service I am currently focusing in teaching Mathematics to the students of Std. 11 an 12th in India. I also mentor the candidates in Mathematics who are preparing for IIT JEE examinations. I have my own coaching institute here in India and have 8 years of extensive experience in teaching Mathematics and Science.
I am also working with Chegg.com as a subject matter expert of Basic Maths ( Precalculus, Prealgebra, Geometry, Trigonometry and Algebra).
