Excellent teaching. Good communication skills, Strong subject knowledge. His friendly approach makes even difficult concepts easy to understand.
My daughter is studying in class 12 and she was attending online class with Mr.Atulya, Physics teacher. We finalised on 3 days per week sessions and also the fixed timings. But for more than one month he has not even bothered to schedule classes as decided and also changed the class timings all of a sudden without any prior notice and also cancelled the scheduled classes also without any notice. But from his profile, I could see that he has all the time for the Demo classes. It's highly irresponsible and unethical of him to cancel classes for more than one month when board exams are very near. I don't want my daughter to attend further classes with an irresponsible teacher.
