With 25+ years of experience teaching Physics at reputed centers like Aakash and Sri Chaitanya

I have taken classes from Udia Sir for my IIT-JEE preparation. He is really good at determining level of his students and build their expertise from there on. He motivated me the entire time and was really patient at explaining difficult topics. He made sure to cover topics at my own learning speed - while at the same time, also motivated me to increase my speed and efficiency over time. I took classes from Sir back in 2009, he didn't use to accept private tutoring at that time - but made an exception for me. I made it to IIT Guwahati, computer science branch. I am highly indebted for his role in my life :)
