Sanjeev Kumar (Rishi Sir) — Physics Teacher for NEET, IIT-JEE, CBSE & ICSE
If your Physics score has been stuck for months no matter how much you study, the problem usually isn’t effort — it’s that formulas were memorised instead of understood. Sanjeev Kumar, known to his students as Rishi Sir, has spent 15+ years fixing exactly this problem for NEET, IIT-JEE, and board exam students across India.
This page covers who he is, how he teaches, what’s included in his courses, and how to start with a free demo class.
Who is Sanjeev Kumar (Rishi Sir)?
Sanjeev Kumar is an M.Sc. Physics (Gold Medalist) educator based in Delhi-NCR, teaching Physics since 2009. Before founding BestPhysicsTeacher.in, he was faculty at Aakash Institute, Narayana, Pathfinder, and Brilliant Tutorials, where he taught Physics to NEET and IIT-JEE aspirants for over a decade before moving to a smaller, more personalised online-and-offline model.
He teaches:
- NEET Physics (Class 11, 12, and droppers)
- IIT-JEE Physics (Mains & Advanced)
- CBSE / ICSE-ISC Physics (Class 9–12)
- BITSAT Physics
Teaching Approach
Rishi Sir’s teaching is built around one core principle: understand the concept, then the formula follows naturally — rather than memorising formulas and hoping they apply correctly under exam pressure.
In practice, this looks like:
- Concept building — every topic starts with the physical idea (why does this happen?), not the equation.
- Derivation, not memorisation — formulas are derived step-by-step so students can reconstruct them if they forget.
- Numerical practice — daily problem-solving, moving from basic to exam-level difficulty.
- Previous year questions (PYQs) — pattern recognition for NEET and JEE-specific question styles.
- Doubt resolution — dedicated sessions so questions don’t pile up chapter after chapter.
- Test + analysis — regular tests followed by error-pattern review, not just a score.
Chapters Covered (NEET & JEE)
- Mechanics — Kinematics, Laws of Motion, Work-Energy-Power, Rotational Motion
- Thermodynamics — Heat, Laws of Thermodynamics, Kinetic Theory
- Electrostatics & Current Electricity
- Magnetism & Electromagnetic Induction
- Ray & Wave Optics
- Modern Physics — Atomic Structure, Nuclear Physics, Semiconductors
Each chapter is taught with derivations, solved examples, and a practice set aligned to NEET or JEE difficulty, depending on the batch.

Online + Offline Access
Classes are available both online (live + recorded, accessible from anywhere in India) and offline at the Delhi-NCR centre for students in the region. This means students from smaller towns and cities can access the same teaching without relocating.

Frequently Asked Questions
Is this course suitable for someone who is weak in Physics?
Yes — the concept-first method is specifically aimed at students who’ve struggled with Physics despite studying hard. A free demo class is the best way to check if the teaching style works for you before enrolling.
Does one course cover both NEET and JEE?
NEET and JEE test Physics differently — NEET rewards speed and direct application, JEE rewards multi-concept problem-solving. Rishi Sir runs separate tracks calibrated to each exam rather than teaching them identically.
Is this useful for Class 9–10 students?
Yes, foundation batches are available for Class 9 and 10 to build fundamentals early, before NEET/JEE-specific preparation begins in Class 11.
Can droppers join mid-year?
Yes, the dropper batch is designed for gap-year students and includes faster-paced revision alongside intensive practice.
Is there a free trial?
Yes — a free demo class is available so you can experience the teaching style before enrolling. Book a free demo class →
Does this cover board exams (CBSE/ICSE) as well as NEET/JEE?
Yes, the combined track covers NCERT-based board preparation alongside competitive-exam-level problem solving, so students aren’t preparing for two separate syllabi in parallel.
