Students Feedback and Reviews

Hear directly from students who have experienced transformative learning by Rishabh Kumar (Freelance, Various Top Tutoring Agency (US, UK, AU, SG based) , Math By Rishabh, MEA).

Rishabh Sir is excellent at teaching Mathematical and Statistical concepts with a deep understanding. His guidance has significantly enhanced my problem-solving skills. Scored full marks 100/100 in many papers, final 95+ in two subjects in very less period of time. Customized learning and flexibility in time help me a lot.

Perfect! Rishabh is very good and well prepared in teaching Maths.
He makes sure that you leave your sessions understanding the content perfectly, explaining each question in great detail and even giving his own tips and tricks on the harder topic. He puts a lot of effort of making study materials as well as continuous learning and improvement. Highly recommended.

Vikas Singh

Maths is about understanding and teaching method should be like which enforces to think, which leads to critical thinking and enhance problem solving skill.

Anamika Singh

Rishabh Sir has truly transformed my academics. His deep understanding of concepts and ability to push me to work harder have made a significant impact on my learning journey. He teaching style is awesome just following him, completing the task, and his tests or exams are extremely conceptual and feedback on it, helps me a lot to improve my math and advance my problem-solving as well as learning skill.

Amrita Kumari

Learn from him, is my luck and his hand-writing is not so good but, understanding is at another level. He made my professor’s material, how to understand the concept and how they are correlated. I got highest score in both papers and in one paper, got full 100 marks. Placed for Intern as I performed well in Interview. Rishabh Sir, has advanced understanding of Statistics, Time Series Analysis, and can correlate with Data Science, Finance, and much more. Being from Social Science background, he can bring the concepts from very basics but, be patient as all these things takes a lot of time.

Joseph Bleahen
University College Dublin (UCD)

Rishabh Sir, has another level of Mathematics Teaching Skill with deep expertise in Mathematics, as expected being an alumnus of IIT Guwahati and the Indian Statistical Institute. He offers Structured Math Lessons for each topics, right from prerequisite, basics to mastery, along with background of the concept, to advanced problem-solving. But, he gives a lot of work, which pushes my boundary. Secured first rank in school, class 10th board.

Shubhadra Singh

I am good at Maths but, when I came across Rishabh’s Sir then, initially, I thought he is usual math teacher but, after few sessions, he puts various cross questions, then problems on that concepts. Then, I realized he is Genius at Mathematics as I go further, I developed strong Mathematical problem solving skill, as he gives a lot of tasks. His class is full of fun engaging and tells many short stories but, somehow they are related with the concepts, and it keeps our sessions engaging, attentive, and enjoyful.
