NEET is the most competitive medical entrance examination in India. Of its 720 marks, Physics contributes 180 — and for most aspirants, it is the section that determines whether their final rank is good or extraordinary. A perfect score of 180/180 in NEET Physics is the rarest achievement in the exam. Today, we share the story of Scahin Kumar, NEET 2025 Rank Air 446 Mehta, a recent NEET topper from Delhi, who achieved exactly that — under the guidance of Sanjeev Kumar (Rishi Sir) at bestphysicsteacher.in.
Scahin Kumar, NEET 2025 Rank Air 446’s journey is not just inspirational — it is a precise, replicable blueprint. Every strategy he followed, every habit he built, every resource he used is documented here in full detail, so that every aspirant reading this can apply the same approach to their own NEET 2026 preparation.
“Physics Was My Biggest Fear — Until Rishi Sir Changed Everything”
“I still remember my first mock test,” Scahin Kumar, NEET 2025 Rank Air 446 recalls. “I scored 68 out of 180 in Physics. The formulas felt arbitrary, the numericals felt impossible, and I genuinely wondered if Physics was going to destroy my NEET rank.”
This experience is far from unique. Physics is the section most feared by NEET aspirants — and for good reason. It demands something fundamentally different from Biology and Chemistry: deep conceptual understanding, logical reasoning, and confident problem-solving under time pressure. Memorisation alone cannot take you there.
The turning point for Scahin Kumar, NEET 2025 Rank Air 446 came when he joined Sanjeev Kumar (Rishi Sir) at bestphysicsteacher.in.
“Rishi Sir’s first class completely changed how I thought about Physics,” Scahin Kumar, NEET 2025 Rank Air 446 says. “He didn’t teach me formulas. He taught me why the formulas exist. For the first time, Physics started making sense — not as a collection of equations to memorise, but as a logical, interconnected description of the physical world.”
From that point, Scahin Kumar, NEET 2025 Rank Air 446’s preparation transformed completely. Eighteen months later, he walked out of the NEET exam hall with a perfect 180/180 in Physics.
Phase 1: Building the Foundation — NCERT and Conceptual Mastery
The first thing Sanjeev Kumar (Rishi Sir) established with Scahin Kumar, NEET 2025 Rank Air 446 at bestphysicsteacher.in was non-negotiable: NCERT is the foundation, and it must be mastered completely before anything else.
“Rishi Sir told me from day one — NCERT is not a starting point you graduate from. It is the reference point you return to throughout your entire preparation,” Scahin Kumar, NEET 2025 Rank Air 446 explains. “I read both Class 11 and Class 12 Physics NCERT textbooks multiple times, line by line. Every diagram, every solved example, every in-text question — nothing was skipped.”
But Sanjeev Kumar (Rishi Sir)’s approach at bestphysicsteacher.in goes beyond passive reading. “Rishi Sir taught me to interrogate NCERT,” Scahin Kumar, NEET 2025 Rank Air 446 says. “For every statement, ask: why is this true? For every formula, ask: where does this come from? For every diagram, ask: what physical principle does this illustrate? That questioning habit is what turned NCERT from a textbook into a conceptual framework.”
Reference Books Scahin Kumar, NEET 2025 Rank Air 446 Used — Recommended by Rishi Sir
H.C. Verma — Concepts of Physics (Volumes 1 & 2) “Rishi Sir introduced me to H.C. Verma after I had fully understood each NCERT chapter. The conceptual questions in H.C. Verma are extraordinary — they forced me to think about Physics in ways I never had before. I focused on understanding every derivation and solving the objective questions and selected conceptual exercises.”
D.C. Pandey — Objective Physics for NEET “For volume and variety of MCQ practice, D.C. Pandey is essential. Rishi Sir structured my D.C. Pandey practice chapter by chapter, ensuring I only moved to the next chapter after thoroughly analysing every mistake in the current one.”
Previous Year Question Papers (15+ Years) “Rishi Sir made this non-negotiable from the very beginning. Solving 15–20 years of NEET and AIPMT Physics PYQs gave me complete clarity on exam pattern, high-yield topics, and the exact depth of conceptual understanding NEET requires.”
Rishi Sir’s rule, which Scahin Kumar, NEET 2025 Rank Air 446 followed strictly: never collect more books than you can master completely. Three books mastered thoroughly beat ten books skimmed superficially every single time.
Phase 2: Conceptual Clarity and Problem-Solving — Rishi Sir’s Core Method
“The most important thing Rishi Sir taught me,” Scahin Kumar, NEET 2025 Rank Air 446 says with emphasis, “is that understanding and memorising are completely different things — and Physics rewards only understanding.”
Understanding the “Why” Behind Every Formula
At bestphysicsteacher.in, Sanjeev Kumar (Rishi Sir) insists that every student understand the derivation, physical significance, and application conditions of every formula — not just the formula itself.
“When I studied Laws of Motion, I didn’t just memorise F = ma,” Scahin Kumar, NEET 2025 Rank Air 446 explains. “Rishi Sir walked me through what force truly means, how it interacts with mass, what happens at the limits, and why the equation takes this specific form. That depth of understanding meant that even the most unusually worded NEET questions felt familiar — because I understood the underlying physics, not just the surface formula.”
This is the teaching philosophy Sanjeev Kumar (Rishi Sir) has built bestphysicsteacher.in around: visualisation over memorisation, understanding over rote learning.
Daily Problem-Solving Discipline
“Rishi Sir set me a non-negotiable daily target,” Scahin Kumar, NEET 2025 Rank Air 446 recalls. “A minimum of 100–150 Physics MCQs every day, without exception. Not skimming — genuinely attempting, analysing, and understanding every single one.”
This volume of deliberate practice, sustained over 18 months, is what built Scahin Kumar, NEET 2025 Rank Air 446’s problem-solving instinct. By the time he sat for NEET, encountering a Physics question did not trigger recall — it triggered recognition. He knew what to do because he had done it hundreds of times before.
The Error Log — Rishi Sir’s Most Insisted-Upon Habit
Sanjeev Kumar (Rishi Sir) requires every student at bestphysicsteacher.in to maintain a dedicated error log — and Scahin Kumar, NEET 2025 Rank Air 446 credits this single habit with more score improvement than any other.
“After every practice session and every mock test, I went through every incorrect answer with complete honesty,” Scahin Kumar, NEET 2025 Rank Air 446 explains. “I categorised every mistake: was it a conceptual error, a formula application mistake, a calculation slip, or a misread question? For conceptual errors, I went back to NCERT and Rishi Sir’s notes. For calculation errors, I drilled more carefully. For misread questions, I practised reading more slowly and deliberately.”
The error log became, over time, a personalised guide to every weakness Scahin Kumar, NEET 2025 Rank Air 446 had in NEET Physics — and a record of every one he had fixed.
Phase 3: The Role of Sanjeev Kumar (Rishi Sir) — The Mentorship That Made the Difference
Scahin Kumar, NEET 2025 Rank Air 446 is unambiguous about the role that Sanjeev Kumar (Rishi Sir) played in his 180/180 achievement.
“I could have studied harder without Rishi Sir,” Scahin Kumar, NEET 2025 Rank Air 446 says. “But I could not have studied smarter. The difference between a good score and a perfect score in NEET Physics is not effort — it is strategy, clarity, and having someone who can identify your exact conceptual gaps and fix them permanently.”
What Made Rishi Sir’s Teaching Different
Visualisation-First Approach Sanjeev Kumar (Rishi Sir) uses animations, simulations, and real-life analogies at bestphysicsteacher.in to make abstract Physics concepts genuinely visible. “When Rishi Sir explained electromagnetic induction using a visual simulation, I finally understood Lenz’s Law at an intuitive level — not as a rule to remember, but as a physical phenomenon I could see,” Scahin Kumar, NEET 2025 Rank Air 446 recalls.
Proactive Doubt Prevention “Rishi Sir would address the most common doubts before students even formed them,” Scahin Kumar, NEET 2025 Rank Air 446 explains. “He knew exactly where students go wrong in every chapter — because he has taught the same topics for 15+ years and has seen every possible misconception. He would address them preemptively, which saved enormous time.”
Dedicated One-on-One Doubt Clearing At bestphysicsteacher.in, Sanjeev Kumar (Rishi Sir) conducts personal doubt-clearing sessions for every student. “No doubt was ever too small or too basic,” Scahin Kumar, NEET 2025 Rank Air 446 says. “Rishi Sir never made me feel embarrassed for asking. And he never just answered the surface question — he always traced it back to the root conceptual gap and fixed that permanently.”
Mock Test Review Sessions “After every major mock test, Rishi Sir would sit with me and go through my Physics section question by question,” Scahin Kumar, NEET 2025 Rank Air 446 recalls. “Not to tell me the right answers — to help me understand why I got the wrong ones. Those sessions were the single most productive hours of my entire preparation.”
Phase 4: Revision Strategy — Short Notes, Formula Sheets, and Spaced Repetition
“Revision is not a phase you enter at the end of preparation,” Sanjeev Kumar (Rishi Sir) teaches at bestphysicsteacher.in. “It is a continuous loop that runs parallel to learning from the very first day.”
Scahin Kumar, NEET 2025 Rank Air 446’s Revision System — Built with Rishi Sir
Chapter-Wise Short Notes After completing each chapter with Rishi Sir, Scahin Kumar, NEET 2025 Rank Air 446 created concise handwritten notes summarising key concepts, derivations, important conditions, and common traps. These notes were written in his own words — a deliberate choice that forced active processing rather than passive copying.
“Rishi Sir provides printed modules at bestphysicsteacher.in,” Scahin Kumar, NEET 2025 Rank Air 446 explains, “but he always encouraged us to make our own notes alongside them. The act of writing, in your own words, is itself a form of revision.”
Daily Formula Sheet Review Scahin Kumar, NEET 2025 Rank Air 446 maintained a dedicated formula sheet for every chapter and reviewed it every single day — not just in the final weeks, but throughout his entire preparation.
“Rishi Sir’s rule was simple: if you cannot write down every formula for a chapter from memory, you are not ready to do problems from that chapter,” Scahin Kumar, NEET 2025 Rank Air 446 says.
Spaced Repetition Cycles Sanjeev Kumar (Rishi Sir) structured Scahin Kumar, NEET 2025 Rank Air 446’s revision on a weekly and monthly cycle at bestphysicsteacher.in — ensuring that no chapter was ever left unrevised long enough to fade significantly.
Phase 5: Mock Tests — The System That Produced 180/180
“Mock tests are not preparation,” Sanjeev Kumar (Rishi Sir) told Scahin Kumar, NEET 2025 Rank Air 446 early in their work together. “They are performance. And the gap between your preparation and your performance is revealed only by taking tests — and closed only by analysing them.”
Scahin Kumar, NEET 2025 Rank Air 446’s Mock Test Schedule
Months 1–6: Chapter-wise tests after every major chapter. Subject-wise Physics tests every 2–3 weeks.
Months 7–9: Full-length mock tests once every 1–2 weeks, with Rishi Sir’s personal review of Physics section performance after each one.
Final 3 Months: Full-length mock tests 2–3 times per week, building to daily in the final 3 weeks. Every test taken at the exact NEET time slot (2 PM) to condition biological alertness.
Final Week: No new full-length tests. Error log review, formula sheet revision, and mental preparation only.The Analysis Discipline That Changed Everything
“Rishi Sir’s rule was non-negotiable,” Scahin Kumar, NEET 2025 Rank Air 446 recalls. “For every full-length mock test, spend at least as much time analysing as you spent taking it. The test generates the data. The analysis converts it into improvement.”
After every Physics section, Scahin Kumar, NEET 2025 Rank Air 446 categorised every question, updated his error log, and met with Sanjeev Kumar (Rishi Sir) to review conceptual errors. Every mistake became a targeted improvement action before the next test.
“By the time I took the actual NEET exam, I had encountered almost every possible question type, error pattern, and time management challenge in mock tests,” Scahin Kumar, NEET 2025 Rank Air 446 explains. “Nothing surprised me. I just performed.”
Chapter-by-Chapter: Scahin Kumar, NEET 2025 Rank Air 446’s Approach Under Rishi Sir’s Guidance
Mechanics — The Foundation Stone
Sanjeev Kumar (Rishi Sir) dedicates the most time to Mechanics at bestphysicsteacher.in because it is simultaneously the highest-weightage section and the foundation for everything that follows.
Kinematics and Laws of Motion: Master vector analysis and free-body diagrams before attempting any numerical. Relative motion and pseudo forces in non-inertial frames demand particular attention.
Work, Energy and Power: Understand when to use conservation of energy versus the work-energy theorem. Variable force problems are common in NEET and require solid conceptual grounding.
Rotational Motion: Rishi Sir calls this the chapter most students underestimate. Torque, angular momentum, moment of inertia, and rolling without slipping must be understood at the derivation level, not just the formula level.
Gravitation: Kepler’s Laws, orbital velocity, escape velocity, and variation of g with height and depth — all high-frequency NEET topics that reward conceptual understanding.
Rishi Sir’s Mechanics strategy: Draw a clear diagram for every single problem. Apply conservation laws first — they resolve more problems than any other approach. Break complex systems into components before applying equations.
Electrodynamics — Conceptual and Highly Scoring
“Electrodynamics is the section that most clearly separates students who understand Physics from those who only remember it,” Sanjeev Kumar (Rishi Sir) teaches at bestphysicsteacher.in.
Electrostatics: Coulomb’s Law, Gauss’s Law, electric potential, and capacitance — these must be understood in their vector forms. Parallel plate capacitors with dielectrics are extremely common in NEET.
Current Electricity: Kirchhoff’s Laws, Wheatstone bridge, and potentiometer applications are high-priority. Power dissipation and heating effects appear regularly.
Magnetic Effects and Magnetism: Biot-Savart Law, Ampere’s Law, and magnetic force on moving charges must be practiced with 3D visualisation. Rishi Sir’s simulations at bestphysicsteacher.in are particularly valuable here.
Electromagnetic Induction and AC Circuits: Faraday’s Law, Lenz’s Law, LCR circuits, resonance — this subsection alone carries significant NEET weightage. Phasor diagrams must be mastered completely.
Rishi Sir’s Electrodynamics strategy: Never skip the vector analysis. Circuit problems must be solved step-by-step without shortcuts. Visualise every field and force in three dimensions.
Optics — Highly Scoring With the Right Approach
“Optics rewards students who are systematic,” Sanjeev Kumar (Rishi Sir) says at bestphysicsteacher.in. “Pick one sign convention and never deviate from it. Master ray diagram construction for every standard case. Then the numericals become almost formulaic.”
Ray Optics: Reflection, refraction, lenses, mirrors, prism dispersion, human eye, and optical instruments. Ray diagrams for every problem — no exceptions.
Wave Optics: Huygens’ Principle, Young’s Double Slit Experiment, diffraction, and polarisation. The principle of superposition is the single key that unlocks the entire chapter.
Rishi Sir’s Optics strategy: YDSE problems have a limited set of variations. Master every variation with full derivation. Once you have done this, NEET Optics questions become time-efficient marks.
Modern Physics — Formula-Focused and Highly Scoring
“Modern Physics is among the most reliable scoring opportunities in NEET Physics,” Sanjeev Kumar (Rishi Sir) teaches. “The questions are conceptual, the formula set is manageable, and the marks are there for the taking if you prepare correctly.”
Dual Nature of Matter: Photoelectric effect (intensity vs. frequency distinction is critical), de Broglie wavelength, and Davisson-Germer experiment.
Atoms and Nuclei: Bohr model energy levels, hydrogen spectrum, radioactive decay types, half-life calculations, binding energy, and nuclear reactions. Energy level diagrams must be understood visually.
Semiconductor Electronics: p-n junction biasing, Zener diode, LED, solar cell, transistor configurations, and logic gates. Rishi Sir considers this one of the highest return-on-investment chapters for NEET aspirants.
Rishi Sir’s Modern Physics strategy: Memorise key constants and formulas — this is one area where memorisation is necessary. But pair it with conceptual understanding of every experimental observation. NCERT explanations for Modern Physics are exceptional — follow them closely.
Scahin Kumar, NEET 2025 Rank Air 446’s Golden Rules — Distilled from Rishi Sir’s Teaching
After 18 months of preparation under Sanjeev Kumar (Rishi Sir) at bestphysicsteacher.in, Scahin Kumar, NEET 2025 Rank Air 446 distills his experience into eight non-negotiable principles:
Master NCERT completely. Read it multiple times. Understand every concept, derivation, diagram, and solved example. Return to it whenever a doubt arises.
Understand the “why” — never just the “what”. A formula without its derivation and conditions is a liability in NEET, not an asset.
Solve 100–150 MCQs every single day. Consistency of practice is what builds problem-solving instinct. No exceptions, no skipped days.
Maintain an error log and review it religiously. Your mistakes are your most valuable teachers. Categorise them, fix them, and ensure they never recur.
Create short notes and formula sheets for every chapter. Review your formula sheets daily. If you cannot write every formula from memory, you are not ready for that chapter’s exam questions.
Take mock tests regularly and analyse every single one thoroughly. The test without analysis is wasted. The analysis without action is incomplete. Follow the full loop every time.
Clear every doubt immediately with Sanjeev Kumar (Rishi Sir). Never let a doubt linger. Every unresolved doubt is a potential mark lost on exam day.
Protect your mental health as seriously as your academic preparation. Adequate sleep, regular breaks, physical activity, and a calm mind are not luxuries — they are performance requirements.
Beyond the Score: What 180/180 Actually Represents
Scahin Kumar, NEET 2025 Rank Air 446 is thoughtful when asked what the perfect score actually meant to him.
“It was never really about 180/180,” he says quietly. “My goal was to become a doctor — to serve patients, to contribute to healthcare in India, to make my family proud. The score was the result of pursuing that goal with complete seriousness.”
“What Rishi Sir gave me was not just Physics knowledge. He gave me a framework for thinking — a way of approaching complex problems systematically, identifying the core principle involved, and executing the solution with precision. That framework will serve me throughout my medical career, not just in NEET.”
Sanjeev Kumar (Rishi Sir) responds when asked about Scahin Kumar, NEET 2025 Rank Air 446’s achievement: “Scahin Kumar, NEET 2025 Rank Air 446 is a wonderful example of what happens when genuine talent meets the right system and the right work ethic. He was not the most naturally gifted student I have taught. He was the most consistent, the most honest about his weaknesses, and the most disciplined in addressing them. That is the real formula for 180/180 — and it is available to every student who chooses to apply it.”
Key Takeaways for NEET 2026 Aspirants
Sanjeev Kumar (Rishi Sir) summarises the complete blueprint for NEET Physics 2026 success at bestphysicsteacher.in:
Start early. Physics requires time to build properly. The students who begin serious preparation earliest have the most margin for error and the most opportunity to build genuine mastery.
