My name is Munish Gupta and i have a teaching experience of 15 years to teach Mathematics and preparing students for NTSE competitive exams. I have my own academic institution and taking classes for more than 100 students.
This channel had been started to teach Mathematics to Class 7, 8, 9, 10, 11, 12 for CBSE and ICSE Board.
I will be teaching with very basic understanding and will cover NCERT(CBSE) and ML Aggarwal(ICSE).
After completion of the chapter from the books I will be sharing Daily Practice Papers for practice and study material also.
I wish I can be good free source to the learners who are keen to learn.
I wish all the best to all my students.

A boy whose eye level is 1.35 m from the ground, spots a balloon moving with the wind in a horizontal line at some height from the ground. The angle of elevation of the balloon from the eyes of the boy at an instant is 60°. After 12 seconds, the angle of elevation reduces to 30°. If the speed of the wind is 3m/s then find the height of the balloon from the ground. (Use √3 = 1.73)

Sir you are always preparing videos for us and also put your lot of effort and time in creating and helping the students. Sir you are not getting many views or subscribers but you have a dedication for providing a free educational source for the student and I appreciate and salute your efforts 🙏 🙏 🙏 👍 😊😊❤❤
Hi Rohit, Thank you so much for appreciating my TH-cam video. It means a lot to me when students find value in my content. While it's true that my channel currently has fewer subscribers, I firmly believe that when you focus on doing good deeds, results will naturally follow in time. For me, success isn't about numbers-if even one of my lectures contributes positively to someone's academic journey, that alone makes me feel deeply fulfilled. I’m committed to growing and improving my content for students like you. Thanks again for your kind words and support! Best regards, Munish Gupta
