Hi, I'm Koustubh.

MS Physics (UT Dallas)|MS Astronomy (IIST)|B.Tech, ECE (NIT Silchar)

I was the lead physics teacher at KIPP DC College Prep in Washington, DC, USA, and I tutor physics and math, primarily at the school level but also introductory college courses. Scroll to know more.

From AP parents

Fear to love for physics.

Real words from parents in Connecticut, Seattle and Atlanta.

“I was a little hesitant when we first started classes for my son with Mr. Koustubh, as I wasn't sure how well it would align with his learning pace and style. My son is an independent learner who typically prefers to work through concepts on his own and rarely seeks help from others. However, as the subjects became more complex, Mr. K took the time to understand his strengths, support him through challenges, and provide guidance whenever it was needed. I truly appreciate all of Mr. K's efforts, dedication, and willingness to help. His guidance and support has created a positive impact on my son's studies.”

“Koustubh has been amazing, great with concepts, deep dives into the subject and nudges the kids in the right direction relentlessly. The remarkable difference I have seen is that she went from fear to love for physics, and that to me is a mark of a great teacher. He made her do tests from time to time and, most importantly, what I liked the most is he taught her what she needed to, way more than what we asked. I would recommend him any day for math and/or physics AP classes.”
