GRE Physics Subject Test — Complete Guide 2026
Content Specifications • Syllabus • Dates • Fees • Strategy
The GRE Physics Subject Test is the gateway to PhD programmes in Physics at universities in the USA, Canada, Europe, and other countries. Administered by ETS (Educational Testing Service), it tests undergraduate physics mastery across 9 content areas — 100 questions, 2 hours, 3 sessions per year. For Indian physics students: approximately 85% of the GRE Physics syllabus overlaps with CSIR NET and IIT JAM — the exam rewards the same conceptual depth that Indian preparation builds.
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.

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)
🎯 GRE-Specific Preparation Needed
📖 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)
Diagnostic: Take 1 full ETS practice test. Score and identify your weak topics.
Close gaps: Focus on Laboratory Methods, Astrophysics, and any weak classical/QM topics.
Full practice tests timed at 120 minutes. Aim for 80+ questions in time.
Test-day simulation: complete practice papers under exam conditions + review all errors.
