AhaGuru online course was the major reason for my good scores in the Physics papers of JEE (Mains) and IIT JEE (Advanced). In particular, I will always remember the depth to which I understood the concepts of Relative Motion and Newton's Laws. Thank you AhaGuru!

Balaji sir’s AhaGuru courses made me think hard by showing several practical examples. He introduced very intuitive methods to solve the toughest of problems. His techniques to solve a wide variety of problems helped me understand Physics in great depth and built my confidence. Balaji Sir will forever be a huge inspiration to me.

Ahaguru greatly improved my problem solving skills. The videos helped me understand the key concepts and essence of every topic clearly. Video solutions for the exercise questions explained how to solve the problem step by step. The techniques introduced in videos made problem solving very easy for me. It really increased my speed and confidence and helped me clear many competitive exams.

The amount of thought put into the online course is astounding! AhaGuru gave me the thrill of discovering the deapth of each concept. Their problem solving techniques are, of course, legend! Every single question and video solution in the course was aimed at building my understanding. The strong fundamentals helped me tackle complicated problems with confidence and joy, rather than fear and apprehension.

I wake up every morning and immediately open the AhaGuru app. The problems have trained me on outofbox thinking. The videos also explain the solution clearly. I am now able to use these techniques to easily solve lots of problems.

AhaGuru online course is simply the best (and I have tried others). I love the way the videos explain everything so clearly. Questions gradually increase in level, giving me a sense of achievement as I progress. The video solutions are really helpful when I get stuck.
