Er, Savin Sindhu, my physics teacher motivated me and developed my interest in Physics. Thanks to his support and my hard work I could clear Indian National Physics Olympiad and score very well in IIT, JEE, and AIEEE. To all aspirants of JEE, I would like to advise that there is no substitute for hard work, but along with hard work, proper guidance is also necessary. I am really thankful to Physics Simplified. I would never have achieved success without you. Thank you, sir!!
