Who This Tutoring Is For

Sumit’s tutoring is designed for undergraduate and early postgraduate Physics students who need rigorous, concept-driven support from a recently graduated M.Sc. physicist with a strong research and academic record.

  • Undergraduate Physics students studying Quantum Mechanics who are finding the transition from classical to quantum thinking difficult and need a tutor who can build that conceptual bridge clearly and patiently.
  • Students tackling Mathematical Physics — including differential equations, complex analysis, and linear algebra as applied to physical problems — who want a tutor with both the mathematical background and the physics training to connect the two coherently.
  • Undergraduate students in Nuclear Physics or Atomic and Molecular Physics who need clear, structured guidance through topics that many university courses move through too quickly.
  • Students preparing for competitive examinations — including CSIR-NET Physical Sciences, GATE Physics, or JAM Physics — who need thorough coverage of Thermodynamics and Statistical Physics, Quantum Mechanics, and Classical Physics from a tutor with a very recent and high-scoring M.Sc. examination record.
  • Students in Engineering Physics, Applied Physics, or related programmes who need support in Electronics or semiconductor device physics — areas where Sumit’s published research in perovskite solar cell modelling gives him direct applied expertise.
  • B.Sc. Physics students across India and internationally who want a tutor who understands the Indian university physics curriculum from the inside — having recently completed both a B.Sc. at the University of Lucknow and an M.Sc. at DTU with distinction.
  • Students who are interested in computational physics or renewable energy applications of semiconductor physics and want a tutor who has published peer-reviewed research in this area at IOP Science level.

About Sumit S.

Sumit S. graduated in July 2025 with an M.Sc. in Physics from Delhi Technological University (DTU), one of India’s leading technical universities, achieving a CGPA of 9.3 out of 10. His M.Sc. dissertation resulted in a published research paper in Physica Scripta, a peer-reviewed IOP Science journal, on the device modelling and computational optimisation of lead-free perovskite solar cells using SCAPS-1D simulation software. He completed his B.Sc. in Physics and Mathematics at the University of Lucknow between 2019 and 2022. Sumit’s academic record positions him among the strongest recently graduated Physics tutors on the My Physics Buddy platform.

Sumit teaches across a broad range of undergraduate Physics and Mathematics subjects — including Quantum Mechanics, Mathematical Physics, Nuclear Physics, Atomic and Molecular Physics, Thermodynamics and Statistical Physics, Classical Physics, and Electronics. His teaching philosophy prioritises genuine conceptual understanding over formula memorisation — a habit formed through his own research work, where understanding the physical mechanism behind a simulation result was as important as the result itself. Sessions are structured around diagnosing where a student’s understanding breaks down, rebuilding the conceptual framework from a solid foundation, and then working through problems with guided reasoning. Sumit’s background in computational modelling and scientific writing also makes him effective at helping students with lab reports, data analysis, and written assignments that require both technical precision and clear communication.


“Sumit has an exceptional ability to explain difficult topics — Quantum Mechanics in particular — with clarity and patience. He clearly understands the subject at a deep level, and because he finished his M.Sc. so recently, he remembers exactly which parts of the course tripped students up. That combination made a real difference to my exam preparation.”

How Sessions With Sumit Work

  1. Diagnose: Each session opens with a targeted diagnostic. Sumit identifies your current topic, your examination or assignment timeline, and the specific point at which your understanding breaks down — whether that is in setting up a problem, applying the correct mathematical method, or interpreting a physical result. Because he has recently completed the same syllabus at a very high level, he quickly recognises the common sticking points that students encounter.
  2. Rebuild from Foundation: Sumit establishes the conceptual framework before introducing equations. In Quantum Mechanics, this means ensuring that the physical meaning of the wave function, the role of operators, and the measurement postulate are understood before working through the Schrödinger equation. In Thermodynamics and Statistical Physics, it means anchoring entropy and partition functions to physical intuition before tackling ensemble theory derivations.
  3. Derive and Connect: Sumit walks students through key derivations rather than presenting results as given. His research background in computational modelling means he also connects theoretical physics to applied contexts — explaining why the physics of semiconductor band gaps, for instance, matters both for the Quantum Mechanics curriculum and for real-world devices like perovskite solar cells.
  4. Guided Problem Solving: Students work through problems on screen with Sumit providing real-time guidance. The focus is on building a transferable method: identifying what is being asked, selecting the correct principle, setting up the mathematics cleanly, and interpreting the result physically. This structured approach is particularly effective for CSIR-NET, GATE, and JAM examination preparation, where problem-setting speed and method clarity are both essential.
  5. Targeted Feedback: Sumit provides specific feedback on both the conceptual reasoning and mathematical execution in your solutions. Drawing on his own recent high-scoring examination experience and his published research work, he can identify error patterns — conceptual, algebraic, or interpretative — and address each with precision.
  6. Reinforce: Practice problems from standard undergraduate texts and past examination papers are recommended after each session. For students working on assignments or lab reports with a computational component, Sumit can also advise on structure, scientific writing, and data presentation — skills he developed through his IOP-published research paper.
  7. Plan and Accountability: Each session concludes with a confirmed topic plan for the next meeting. For students on a defined examination timeline — CSIR-NET, GATE, university finals — Sumit builds a structured session schedule to ensure all tested areas receive adequate preparation before the exam date.
Whether you are working through undergraduate Quantum Mechanics for the first time, preparing for CSIR-NET or GATE Physics, or needing expert support in Thermodynamics, Nuclear Physics, or Mathematical Physics, Sumit brings a 9.3 CGPA M.Sc. record and published research credentials to every session. Bring your current topic, your exam date, and your hardest problem. Message Sumit on WhatsApp today.
