Best Physics Teacher in India for 12th

Class 12 is the year when everything a student has been building finally gets tested — simultaneously. The CBSE or ISC board exam is happening in March. NEET is in May. JEE Mains has already started from January. A Class 12 Physics student is not preparing for one exam — they are preparing for three different assessments that overlap in syllabus but differ completely in how they test it. The CBSE Class 12 Physics board paper rewards complete derivations, neat diagrams, and structured answers. NEET tests rapid concept application with four options and no partial marks. JEE Mains demands formula accuracy and numerical speed. Managing all three from the same Class 12 Physics syllabus, without dropping marks in any of them, requires a teacher who understands all three formats deeply — not just one. Sanjeev Kumar (Rishi Sir) has been preparing Class 12 Physics students for both boards and competitive exams for over 15 years, and this exact overlap — knowing what boards want versus what NEET and JEE want from the same chapter — is one of the clearest strengths his students consistently mention.

Rishi Sir holds an M.Sc. in Physics with a Gold Medal and began his teaching career at Aakash Institute in 2009, before teaching at Pathfinder and Narayana — institutions with a strong record of producing top board scorers and competitive exam qualifiers across India. Over 15 years of teaching Class 12 Physics, he developed a dual-track approach that runs both board preparation and competitive exam preparation simultaneously through the same chapter, without wasting time teaching the same concept twice in two different ways. Every chapter is taught concept-first, then board-exam style is practiced separately from competitive exam style — so a student preparing for both never feels they are splitting their time between two different subjects.

CBSE Class 12 Physics Syllabus — Chapter by Chapter

The CBSE Class 12 Physics syllabus carries 70 marks in theory and 30 marks in practicals. Understanding what each chapter demands — both for boards and for NEET/JEE — is essential for smart preparation. Unit 1 — Electrostatics (Chapters 1 and 2) covers electric charges, Coulomb’s Law, electric field, electric potential, capacitors and dielectrics. For boards, the derivation of the electric field due to an infinite plane sheet of charge and the energy stored in a capacitor are frequently asked. For NEET, Electrostatics contributes 4 to 6 questions every year, with capacitor combinations and potential energy problems appearing consistently. For JEE, Gauss’s Law applications and capacitor problems with dielectrics are standard. Unit 2 — Current Electricity (Chapter 3) is one of the highest-scoring chapters across all three exams. The derivation of Ohm’s Law on the basis of drift velocity, Kirchhoff’s Laws, the Wheatstone Bridge, and the Potentiometer principle are all board-exam derivations that Rishi Sir teaches with complete step-by-step clarity. In NEET and JEE, circuit simplification problems and internal resistance questions from this chapter appear in almost every paper. Unit 3 — Magnetic Effects of Current and Magnetism (Chapters 4 and 5) introduces Biot-Savart Law, Ampere’s Circuital Law, the moving coil galvanometer, and magnetic properties of materials. The derivation of magnetic field on the axis of a circular current loop using Biot-Savart Law is a classic board question. For competitive exams, force on a current-carrying conductor in a magnetic field and the working principle of a cyclotron are standard topics. Unit 4 — Electromagnetic Induction and Alternating Currents (Chapters 6 and 7) is where many Class 12 students struggle most. Faraday’s Law, Lenz’s Law, self-inductance and mutual inductance, AC circuits with LCR combinations, and resonance — these chapters require both conceptual clarity and comfort with phasor diagrams. The derivation of EMF induced in a rotating coil is asked almost every year in CBSE boards. Rishi Sir spends extra time on this unit because it is the one where gaps from Class 11 (specifically from Waves and Oscillations) show up most visibly. Unit 5 — Electromagnetic Waves (Chapter 8) is conceptually lighter but has specific board and NEET questions around the electromagnetic spectrum, properties of EM waves, and displacement current. Unit 6 — Optics (Chapters 9 and 10) — Ray Optics and Wave Optics — is one of the most important units for both NEET and JEE. Derivations of the mirror formula, lens formula, and lens maker’s equation are standard board questions. Wave optics — Young’s Double Slit Experiment, diffraction, and polarisation — contributes 4 to 6 questions in NEET and appears in JEE Advanced in its more complex forms. Unit 7 — Dual Nature of Radiation and Matter (Chapter 11) introduces the photoelectric effect and de Broglie wavelength. Einstein’s photoelectric equation is a derivation asked in both CBSE boards and explained conceptually in NEET and JEE. Unit 8 — Atoms and Nuclei (Chapters 12 and 13) covers Bohr’s model of the hydrogen atom, nuclear fission and fusion, radioactivity, and binding energy. The derivation of the radius and energy of Bohr’s orbit is a standard board question. For NEET, Modern Physics from these two chapters contributes 6 to 8 questions every year. Unit 9 — Electronic Devices (Chapter 14) covers semiconductors, p-n junction diodes, logic gates, and transistors. This is a chapter where board preparation and NEET preparation align almost completely — understanding the working of a p-n junction in forward and reverse bias, the characteristics of a transistor, and truth tables for logic gates covers both exams simultaneously.

ISC Class 12 Physics covers much of the same content as CBSE but goes deeper into certain mathematical derivations and has a slightly different practical component. Rishi Sir’s Class 12 Physics coaching handles both CBSE and ISC students — ISC-specific derivations and the ISC paper’s longer answer format are practiced separately within the same batch structure, so ISC students are never at a disadvantage.

Live online classes cover each chapter with full board-exam derivations taught first, followed by competitive exam application — so students get both in one session rather than switching between two coaching environments. Every session is recorded for revision. Chapter-wise tests are held after every unit, alternating between board-style long-answer questions and competitive exam multiple-choice format so students stay fluent in both. A full-length board mock test is held before the CBSE practical exam season, and NEET/JEE format mocks run alongside throughout the year. Doubt clearing is available both within the class and on WhatsApp directly with Rishi Sir between sessions. Students from Delhi, Noida, Mumbai, Bengaluru, Kolkata, Hyderabad, Chennai, Patna, and international locations including Dubai and Singapore attend these live sessions every week.

Frequently Asked Questions — Class 12 Physics Coaching

Q1: How does Rishi Sir manage both board exam and NEET/JEE preparation from the same Class 12 syllabus? 

Every chapter is taught in a structured dual-track format. The concept is taught first, then the board-exam approach — full derivations, diagram-based questions, structured long answers — is practiced. The same concept is then applied to competitive exam format through multiple-choice and numerical problems. Students preparing for only boards, only competitive exams, or both are all accommodated within the same batch structure.

Q2: Which derivations are most important for CBSE Class 12 Physics boards? 

The most frequently asked derivations in CBSE Class 12 Physics include the expression for drift velocity and its relation to current, energy stored in a capacitor, magnetic field on the axis of a circular current loop using Biot-Savart Law, EMF induced in a rotating coil in a magnetic field, mirror formula and lens formula, Einstein’s photoelectric equation, and the radius and energy of Bohr’s orbit. Rishi Sir covers all of these in complete step-by-step detail in every batch.

Q3: Does Rishi Sir teach ISC Class 12 Physics students as well? 

Yes. Both CBSE and ISC Class 12 Physics students are taught. ISC-specific derivations, the ISC paper’s longer answer format, and practical-related theory questions are covered separately within the batch so ISC students meet their board requirements fully.

Q4: How many questions in NEET come from Class 12 Physics? 

Approximately 50 to 55 percent of the NEET Physics paper — roughly 22 to 25 questions out of 45 — comes from Class 12 chapters. Electrostatics, Current Electricity, Optics, Modern Physics, and Semiconductor Devices together account for the majority of these questions every year.

Q5: Can a student join the Class 12 batch mid-year? 

Yes. Students joining mid-year are assessed for chapters already covered, and recorded sessions from earlier in the course are shared so gaps can be filled. A personalised catch-up schedule is discussed at the time of joining based on how much of the year has already passed.

Q6: Is a free demo class available? 

Yes. A free demo class is available for all new students. Contact Rishi Sir on WhatsApp at +91 88823 82572 to schedule a session. The demo covers one complete topic so students get a genuine sense of the teaching style and class structure before enrolling.
