GRE Mathematics Subject Test: what it measures

The GRE Mathematics Subject Test is an achievement test for applicants with an undergraduate mathematics major or extensive mathematical background. Graduate departments may use it as one part of an application alongside transcripts, recommendations, research experience and other evidence. This Exams.fit guide is independent and was reviewed against ETS sources on September 13, 2026.

ETS currently describes the Mathematics Subject Test as a computer-delivered exam with approximately 66 multiple-choice questions and a total testing time of 2 hours 50 minutes. There are no separately timed sections. The content comes from mathematics commonly taught at the undergraduate level.

Official Mathematics content distribution

Content area	Approximate share	What to prioritize
Calculus	50%	Single- and multivariable ideas, applications, sequences/series and the calculus foundations used across undergraduate mathematics.
Algebra	25%	Elementary and linear algebra plus abstract algebra and number-theory foundations.
Additional Topics	25%	Other undergraduate areas listed by ETS in the official practice specifications.

The percentages above come from the official ETS content and structure page. Use the current ETS Mathematics Practice Book for the detailed content outline and official sample material.

2026–2027 GRE Subject Test dates

Testing window	Official score reporting date	Planning note
September 14–27, 2026	October 5, 2026	The first 2026–27 testing window.
October 19–November 1, 2026	November 9, 2026	Check application deadlines before choosing a date.
April 19–May 2, 2027	May 10, 2027	Useful for later application cycles or retesting when appropriate.

ETS states that a GRE Subject Test may be taken once every 14 days, including when a previous score was canceled. A published testing window does not guarantee a particular appointment. Use the official ETS scheduling page and the registration system for current appointment availability.

How to build a useful diagnostic

Start with authorized ETS material under realistic timing. Do not begin by memorizing a long formula list. Your first goal is to identify which type of failure costs the most points: missing content, weak theorem recall, algebraic execution, interpretation, proof-style reasoning translated into multiple choice, or pacing.

1. Tag every missed problem by domain. Use calculus, algebra or additional topics first, then a narrower subtopic.
2. Tag the error mechanism. Distinguish concept gap, setup error, manipulation error, forgotten condition, careless arithmetic and time pressure.
3. Re-solve without answer choices. This checks whether recognition of an option was hiding a weak method.
4. Use a fresh transfer problem. A correction is not complete until the same idea works in a different problem.
5. Track time per cluster. A technically correct method may still be too slow for the real test.

High-yield Mathematics preparation order

1. Calculus first

Because ETS assigns about half of the Mathematics test to calculus, a weak calculus base has the largest potential impact. Review limits, continuity, differentiation, integration, sequences and series, multivariable calculus and applications in a connected way. Avoid studying formulas as isolated facts; practice identifying the condition under which a theorem or method is valid.

2. Linear and abstract algebra

Separate computational linear algebra from structural reasoning. For matrices, transformations, vector spaces, eigenvalues and related topics, practice moving between symbolic, geometric and conceptual representations. For abstract algebra and number theory, review definitions and counterexamples as carefully as standard computations.

3. Additional undergraduate topics

Use the current ETS practice specifications to identify the remaining areas actually in scope. Build a checklist from the official outline rather than from a generic mathematics-degree syllabus. Give more time to topics that repeatedly appear in your diagnostic errors.

A 14-day rapid-review plan

Days	Main task	Evidence of progress
1–2	Official diagnostic and error classification	Ranked list of weak domains and pacing bottlenecks
3–6	Calculus repair	Fresh mixed problems solved with written reasoning
7–9	Algebra repair	Fewer definition, setup and manipulation errors
10–11	Additional topics	Coverage checked against the ETS outline
12	Mixed timed blocks	Stable pacing without a sharp accuracy drop
13	Full or near-full authorized rehearsal	Final error list and timing checkpoints
14	Light review and logistics	Confirmed appointment and rested test-day plan

If more time is available, stretch the same sequence and insert spaced mixed review. If less time is available, prioritize the largest repeated error sources instead of trying to cover every textbook chapter.

Scoring and score-use basics

ETS reports a total GRE Subject Test score on a 200–990 scale in 10-point increments, although the practical score range for an individual subject can be narrower. Physics and Psychology also report percent-correct subscores for tests taken beginning in September 2023. ETS states that Subject Test scores are reportable for five years after the individual test date.

Do not treat one practice-test percentage as a guaranteed scaled score. Practice performance is most useful for finding weak domains, pacing problems and recurring reasoning errors. When a graduate department publishes its own score policy, that department's current admissions guidance controls how the score is considered.

Registration and test-day planning

• Create or use the correct ETS account and confirm the exact Subject Test before booking.
• Choose a date that leaves enough time for the official score-reporting date and the receiving institution's processing time.
• Recheck the appointment, identification rules, testing location or at-home requirements, and any approved accommodations in the official ETS system.
• Use the official ETS practice book to learn the real content specifications and official item style. Exams.fit practice should be original supplementary work, not copied or reconstructed ETS questions.
• Keep confirmation details and identification information private; do not place account credentials or sensitive documents in public study notes.
