Physics GRE Study Guide

Independent Physics GRE study guide with undergraduate physics review paths, formula links, calculators, and original practice prompts.

Independent resource: Independent study resource. Not affiliated with or endorsed by ETS. Always confirm current exam rules, official specifications, and official practice materials with the relevant exam body.

Physics GRE preparation rewards breadth, speed, and careful recognition of standard undergraduate models. The safest way to study is to build a formula-and-concept map across mechanics, electromagnetism, quantum mechanics, thermodynamics, statistical physics, optics, special relativity, and laboratory methods, then practise moving quickly between topics.

This guide is independent and is not affiliated with, endorsed by, or sponsored by ETS. For the current test status, registration details, content descriptions, policies, and official practice materials, consult ETS directly.

Study Path

Core Undergraduate Review

Classical mechanics, electromagnetism, waves, optics, thermal physics, and quantum basics.

Speed Practice

Short mixed problems, limiting cases, dimensional analysis, and recognition of common approximations.

Advanced Pass

Lagrangian ideas, Maxwell equations, operators, spin, perturbation thinking, statistical ensembles, and special relativity.

Topics, Formulas, and Calculators

Use this section to move from concept review to formula practice. Each topic links to a guide plus calculators that show units and variable meanings.

Original Practice Prompts

These are original concept checks written for this site. They are not official exam questions and should not be treated as a replacement for official practice materials.

Prompt: A Hamiltonian has two non-degenerate energy levels separated by Delta E. What photon frequency matches the transition?

Check: Use E = hf, so f = Delta E / h.

Prompt: A charged particle moves perpendicular to a uniform magnetic field. What sets the radius?

Check: Magnetic force supplies centripetal force: qvB = mv^2/r, so r = mv/(qB) for perpendicular motion.

Common Mistakes

  • Substituting numbers before converting units.
  • Using a formula without checking its assumptions.
  • Ignoring vector direction, sign convention, or reference level.
  • Memorising answer patterns instead of explaining the physical model.
  • Using unofficial summaries for current exam policy instead of the exam body's own materials.

FAQ

Is this an official ETS guide?

No. It is independent. Use official ETS materials for current test availability, rules, and representative official questions.

Does Physics GRE prep require calculus?

Yes, undergraduate physics fluency usually includes calculus. Some quick questions are algebraic, but calculus-based concepts are part of serious preparation.

Are these official GRE questions?

No. The prompts here are original and are meant for concept checking, not as copies of official test items.
