What viewers say about the channel
A few words left by viewers of Stay Mathactive on YouTube.
“Sir, it’s really great to see how this channel has grown beyond just solving math problems to sharing deeper insights into mathematics and guiding us on how to approach it in the first place. Thank you for teaching us the art of systematic thinking and showing us how to trace connections between ideas across different fields for a single problem that is expected to be solved within that method!”
“Continue your videos sir. I’m currently in IIT Bombay. My math journey started because of you. The way you think and your approach towards the questions are insane. Most of the teachers teach to solve questions but you teach us how to think. I was lucky to have you as my math staff. I give you the credits for my journey. Thank you sir.”
“Brilliant. Your approaches are really commanding as well as very intuitive. I was going through your videos for my son who is a JEE aspirant and I was deeply impressed, although my domain is hardcore organic chemistry at UG and PG level.”
“The instructor delivers the concept with exceptional clarity and elegance, transforming mathematics into something almost poetic in nature. His articulation, choice of vocabulary, and overall presentation reflect a high level of professionalism and intellectual depth.”
“Hello sir, I have always admired and have respect for the way you solve questions by giving an in-depth conceptual understanding.”
“Your videos are mathematically beautiful and AI can’t bring this depth.”
“Most underrated YouTube channel perhaps… sir deserves more recognition.”
“I’m a B.Tech graduate… but I still watch these types of sessions, which just give me a different approach to solve the problems!! Please bring such sessions. Great respect for you sir!!”
“That’s how a real mathematician teaches maths, in just simple language and very deeper meaning ❤”
“Amazing concept!! Wish I had found this channel sooner, now I have got JEE Advanced in 10 days, so I cannot experience the joy of binge watching your videos 😅”
“Wow sir. Recently got recommended your videos. Very good communication and explanation. Enjoyed it.”
“Amazing lecture sir, wish I found your channel earlier. It was very helpful.”
“I just wanted to say thank you for all the hard work you put into these tutorials. They’ve been a lifesaver for my studies!”
“Thanks sir, your support in the last month of my Advanced prep made me a very great help, thanks sir 🙏”
“Thanks a lot sir! ❤❤ And thanks for guiding us through innumerable tough problems.”
“Sir there is only one thing to say, just WOW. You literally open up an entirely new dimension of mathematics by such questions. Blessed to gain this beautiful knowledge 🙏🏻”
“Thanks a lot sir for sharing your experience with us.. 🙏 Really you’re a great teacher sir 👍”
“Sir, please continue this work. Your lecture was awesome and I clearly understood everything. Please don’t stop your work sir.”
“Magician of mathematics, Mr Ashutosh sir”
“Sir jee, aap is gyan sagar ko bahut kam log hi samajh paate honge, kyon ki bahut log jis level tak padh sakte, aapka to wahan se education ka status start hota hai. Bahut sochta hoon ki kaash aapke paas aur din ruk kar aapse gyan arjit kar pata… us teacher-god ko nahi bhool sakta jo meri zindagi aur meri family ki zindagi badal sakta tha.”

I would like to take this opportunity to thank Ashutosh sir for training me in mathematics during my school days. He has been my go-to person for any doubts and was always available to help at any time of the day. He is very student-friendly and an easily approachable person. Currently, I am working as a software engineer at DisneyplusHotstar, and as far as my student life goes, I believe he is one of the best teachers out there for mathematics.

Ashutosh sir is a very competent and approachable teacher who is always inclined and excited about his students' learning. I had a great experience learning Math from him. I grew as a student and an individual under his guidance. I learnt Differential and Integral Calculus, Coordinate Geometry, Complex Numbers, Sequences and Series, Matrices and Determinants, Permutation and Combination, and Probability under Ashutosh sir's guidance and it certainly helped me solidify my fundamental understanding of Mathematics as a subject. He also makes sure to instill a sense of appreciation and admiration for the beauty of Math that he's teaching, which not only makes the learning experience more efficient but also fun. I'm currently pursuing a PhD in Physics in the U.S., and I can certainly attest to the fact that Ashutosh sir has played an instrumental role in my success as a student and a scientist.

Ashutosh Kumar Sir is an exceptional teacher who is deeply passionate about his subject. Learning from him was a transformative experience for me, both academically and personally. His teaching style not only strengthened my conceptual understanding of these topics but also sparked a genuine appreciation for the elegance of Mathematics. I like the way how he use to teach the concepts in the similar manner like MIT Professors David Jerison, Gilbert Strang. "The thing is", he ensures that every concept is well understood, making even the most challenging topics accessible and enjoyable. His ability to relate mathematical ideas to real-world applications made the learning process engaging and rewarding. Though I am not a topper, he made me love maths forever and also he is one of my Inspiration. It was a great opportunity to connect with him during my school days and feeling so proud to be his student . Thanks a lot sir
