Shivendra Singh

Myself Shivendra Singh worked in Kota as Physics Educator almost 10 years now I came in Sultanpur in covid pendemic in 2020. I have felt that students of Sultanpur need real guidance for JEE and NEET so I have started specialized PHYSICS coaching in Shashtri Nagar, Sultanpur for 11th and 12th (CBSE) , IIT-JEE and NEET.
(Mentor and counsellor for IIT-JEE and NEET)
