About Your PNJ Sir

 "Passion is the genesis of genius"

- Galileo Galilei

Hi! I'm Jainam Khara, popularly known as PNJ Sir — a Physics teacher by profession, but a student of curiosity for life. The name PNJ (P for Physics, J for Jainam) was given to me during my time at Lakshya, and it’s grown into a brand — from this blog, to my Instagram page, to every classroom I step into.

I hold a Master's in Physics from IIT Bombay and have been teaching for over 15 years, ever since I first picked up the chalk at the age of 15. My mission has always been to make students fall in love with Physics — not fear it. Because when passion for a subject is ignited, it creates purpose, and purpose pushes you toward your best self.

Currently, I’m teaching at the Vedantu Learning Center at PCMC Pune, which became India’s Best Vedantu Offline Center in just 4 months. I’ve mentored thousands of students for IIT JEE, NEET, and IIT JAM, and many of them are now at IITs, IISERs, and other top institutes.

I also ran a platform called Hub for IIT JAM, authored a JAM Practice Book with 1790+ questions, and enjoy creating numericals with my fictional character Sharad Kaandi — who can’t do the math and needs students’ help. He’s been a comic relief and a learning catalyst for many.

“Develop the passion for Physics from the passionate.”
