Overview

What is the GRE Physics Subject Test?

The GRE Physics Subject Test is administered by Educational Testing Service (ETS) and is designed to assess a candidate’s grasp of fundamental physics principles and ability to apply those principles in problem-solving. It is required for admission to most PhD programmes in Physics at universities in the United States, Canada, and several European institutions.

The test consists of approximately 100 five-choice questions, some grouped in sets based on diagrams, graphs, experimental data, and physical situations. Most questions can be answered on the basis of mastery of the first three years of undergraduate physics. The International System (SI) units is used throughout. A table of physical constants and conversion factors is provided in the test book.

Since April 2021, the GRE Physics Test reports three subscores in addition to the total score: (1) Classical Mechanics, (2) Electromagnetism, and (3) Quantum Mechanics & Atomic Physics. These subscores allow graduate programmes to assess topic-specific strengths.

🌎 For Indian Physics Students

Approximately 85% of the GRE Physics syllabus directly overlaps with CSIR NET Physical Sciences and IIT JAM Physics. Students who have cleared or seriously prepared for CSIR NET / IIT JAM arrive at GRE Physics preparation with most of the conceptual foundation already in place. The primary GRE-specific gaps are Laboratory Methods and certain Astrophysics topics.

A strong total score of 900+ is generally needed for top US Physics PhD programmes (MIT, Caltech, Stanford, Princeton). 800+ is competitive for most strong programmes.

Subscore 1: Classical Mechanics

Kinematics, Newton’s laws, Lagrangian & Hamiltonian, oscillations, fluid dynamics — 20% of total

Subscore 2: Electromagnetism

Electrostatics, circuits, magnetic fields, Maxwell’s equations, EM waves — 18% of total

Subscore 3: QM & Atomic Physics

Schrödinger equation, spin & angular momentum, Bohr model, atomic spectra, selection rules — 22% combined

💡 No negative marking: Unlike CSIR NET, the GRE Physics Subject Test has no penalty for wrong answers. Always attempt every question. The scoring formula only counts correct answers — there is no deduction for incorrect or unanswered questions.

Strategy for Indian Students

GRE Physics Preparation Strategy for CSIR NET / IIT JAM Students

For Indian physics students who have prepared for CSIR NET or IIT JAM, approximately 85% of the GRE Physics content is already familiar. The strategy is to build on existing preparation — not start from scratch.

✅ Your Existing Strengths (from CSIR NET / IIT JAM)

Classical Mechanics — Lagrangian, Hamiltonian, central force: directly tested
Electromagnetic Theory — Maxwell’s equations, EM waves, boundary conditions: excellent overlap
Quantum Mechanics — Schrödinger, operators, perturbation theory: strong base
Thermodynamics & Statistical Mechanics — laws, partition functions, ensembles: well-covered
Atomic Physics — Bohr model, spectra, Zeeman effect: directly maps to CSIR NET A&M
Special Relativity — Lorentz transformations, mass-energy: standard Indian exam content
Wave Phenomena — interference, diffraction, polarisation: IIT JAM Optics content
No negative marking — unlike CSIR NET, attempt every question confidently

🎯 GRE-Specific Preparation Needed

Laboratory Methods (6%) — not tested in CSIR NET or IIT JAM. Focus on: error analysis, data analysis, electronics (oscilloscopes, lock-in), radiation detectors, counting statistics
Astrophysics basics (within Specialized Topics) — stellar physics, Hertzsprung-Russell diagrams, basic cosmology at conceptual level
Computer applications in physics (within Specialized Topics) — numerical methods, basic computational physics
GRE-specific question style — grouped question sets, graph-interpretation, lab-data problems require specific practice
Timing — 100 questions in 120 minutes = 72 seconds per question. Speed under time pressure must be trained separately

📖 Best GRE Physics preparation books: “Conquering the Physics GRE” (Yoni Kahn & Adam Anderson) + ETS Official Practice Tests. Use Griffiths (E&M, QM), Taylor (Classical Mechanics), and Kittel (Solid State) as reference, not as primary preparation texts.

📅 Recommended Preparation Timeline (for Indian students with CSIR NET / IIT JAM foundation)

Weeks 1–2

Diagnostic: Take 1 full ETS practice test. Score and identify your weak topics.

Weeks 3–6

Close gaps: Focus on Laboratory Methods, Astrophysics, and any weak classical/QM topics.

Weeks 7–9

Full practice tests timed at 120 minutes. Aim for 80+ questions in time.

Weeks 10–12

Test-day simulation: complete practice papers under exam conditions + review all errors.

FAQ

GRE Physics Subject Test — Frequently Asked Questions

Dates, fees, overlap with Indian exams, scoring, negative marking, and target scores — answered.

The GRE Physics Subject Test is administered by ETS and is designed to measure undergraduate physics mastery. It is required for admission to most PhD programmes in Physics in the USA, Canada, and several European countries. Any physics graduate or MSc student planning to apply for international PhD programmes in physics should take it. The test consists of ~100 five-choice MCQs over 2 hours, covering 9 content areas weighted by undergraduate physics curriculum emphasis.
GRE Subject Tests are offered in three windows per year. Confirmed 2025–26 windows: September 8–21, 2025 (completed); October 13–26, 2025 (completed); April 20–May 3, 2026 (upcoming). The 2026 September and October windows will be announced by ETS — check ets.org for exact dates. In India, the test is available at Prometric test centres in New Delhi, Mumbai, Bengaluru, Chennai, Hyderabad, Kolkata, Pune, and other cities. At-home testing is not available in India for Subject Tests.
The GRE Physics Subject Test fee is approximately ₹14,500 in India (approximately $150 USD globally). Additional fees: Rescheduling or changing test centre costs $50. Additional score reports beyond the first 4 cost $35 each. On test day, you can select up to 4 institutions to receive score reports for free. Always verify the current fee at ets.org before registering — fees are subject to change by ETS.
GRE Physics and CSIR NET / IIT JAM share approximately 85% of their content: Classical Mechanics (Lagrangian, Hamiltonian), Electromagnetic Theory (Maxwell’s equations, EM waves), Quantum Mechanics (Schrödinger, perturbation theory), Thermodynamics & Statistical Mechanics, Atomic Physics (Bohr model, spectra, Zeeman effect), Special Relativity, and Wave Phenomena. The primary GRE-specific content not in Indian exams is Laboratory Methods (6%) — error analysis, instrumentation, radiation detection — which requires 2–3 weeks of targeted preparation.
No — the GRE Physics Subject Test has no negative marking. Unlike CSIR NET (which has −25% penalty) or IIT JAM Section A (which has −1/3 or −2/3 penalty), GRE Physics only counts correct answers. There is no deduction for incorrect or unanswered questions. This means you should always attempt every question — even a random guess has a 20% chance of scoring (5 choices per question).
Score requirements vary by programme: 900+ (out of 990) for top-10 programmes like MIT, Caltech, Stanford, Princeton, Harvard, Chicago. 800+ for most strong research programmes (rank 10–50). 700+ for many good programmes. Scores are also reported as percentile ranks — a 900+ score is typically in the 90th+ percentile. The three subscores (Classical Mechanics, Electromagnetism, QM & Atomic Physics) also matter — a well-rounded score is better than a high total with a weak subscore.
