I am graduated in Physics in 2018, from KIRORIMAL COLLEGE, University of Delhi. Now I am persuing Master's degree in physics. I like to do physics problems. I have experience of 1 year in tutoring. I think Physics is the only subject where you understand things,how they are happening . In physics you learn Maths and apply it. So I would like to join your platform to solve many Physics problems.
