MathStats Classes is primarily led by its founder, Dr. Santosh Kumar Chaudhary (often called Santosh Sir), an alumnus of IIT Kharagpur with a PhD and impressive ranks like AIR 3 in GATE and AIR 17 in IIT JAM. He is widely recognised for his ability to simplify complex statistical concepts for exams like CSIR-NET and ISS. Alongside him, the platform employs a specialized team of doubt-clearing faculties who assist students through dedicated live sessions and interactive app features. This combination of high-level academic expertise from Dr. Chaudhary and consistent support from assistant instructors is a key reason for the platform's strong track record in producing top-ranking students. Parimal Sir is a core mathematics faculty member at MathStats Classes, where he specializes in teaching the essential mathematical foundations required for statistics-heavy exams like IIT JAM MS and GATE. An alumnus of IIT Delhi currently pursuing his PhD, he is primarily responsible for subjects such as Calculus, Ordinary Differential Equations, and Sequence & Series. Students often highlight his "One Shot" marathon revision sessions and his focus on solving Previous Year Questions (PYQs) as being particularly helpful for grasping complex topics quickly. His presence on the team provides a strong mathematical balance to the statistics expertise offered by Dr. Santosh Kumar Chaudhary. Mobile : 8810409392
