About this exam

The GRE Subject Tests are a family of graduate-admissions assessments produced by ETS, the organization behind the GRE General Test. ETS describes this line of products as measuring critical skills for success in thousands of graduate programs, and it lists the GRE Subject Tests alongside the GRE General Test under graduate admissions. Candidates typically take a Subject Test when a department, program, or fellowship asks for evidence of depth in a specific discipline beyond the General Test, or when they want to strengthen an application to a quantitatively or scientifically demanding program. Because a Subject Test targets a single field, preparation differs from General Test prep: you are revising a body of coursework rather than drilling verbal and analytical reasoning. Sensible preparation means obtaining the official practice materials for your subject, sitting a full-length practice test under timed conditions early to find weak areas, then rebuilding those areas from a standard textbook before returning to timed practice. This page is an independent study resource and is not affiliated with, endorsed by, or sponsored by ETS; always confirm registration deadlines, fees, test dates, scoring, and permitted calculators directly with ETS before you commit money or travel plans. Details such as the number of questions, the time limit, and the score scale are set by ETS and can change between administrations.

Common questions

About GRE Math Subject Test preparation

Who publishes the GRE Subject Tests, and are they the same as the GRE General Test?

ETS publishes both. The General Test measures verbal reasoning, quantitative reasoning, and analytical writing and is used across many fields. Subject Tests are separate assessments tied to a single discipline, intended to show depth in that subject. They are distinct products with their own registration, dates, and score reporting, so check the ETS GRE pages for the subject you need.

How many Subject Tests are there, and which one should I take?

Take the one your target departments ask for, not the one you find easiest. Programs state their requirements on their admissions pages, and some accept the General Test only. Confirm with the department before registering, because a Subject Test score you did not need costs you study time and a fee you cannot recover.

How long is the test, how many questions does it have, and what score do I need?

Those specifics are set by ETS and are not stated in the source material used for this page, so treat any figure you see elsewhere as unverified until you read it on the official ETS site for your subject. The same applies to score scales and percentile tables. Confirm all of it on ets.org before you plan your timing or set a target score.

How hard is a Subject Test compared with the General Test?

Expect coursework-level difficulty. The General Test rewards reasoning you can sharpen with general practice; a Subject Test samples a defined undergraduate curriculum, so gaps in specific topics hurt more than general test-taking skill. Candidates usually find the pace, not the individual questions, to be the main obstacle, which is why timed full-length practice matters.

How should I structure my study time?

Start with one timed full-length practice test to get a baseline and expose weak topics. Then work through those topics from a standard textbook, doing problems rather than rereading. Return to timed sections in the final weeks to fix pacing. Keep an error log of every miss and the reason, and revisit it weekly rather than accumulating new material you never consolidate.

What are the most common ways candidates lose points?

Running out of time because they linger on one hard question; skipping the review of a topic they assumed they knew from an old course; and practising untimed, which hides pacing problems. Another frequent error is preparing from vague memory of the syllabus instead of the official topic list and practice materials published by ETS for that subject.

Can I retake the test, and how often?

Retake rules, waiting periods, and how scores are reported or chosen are set by ETS and are not stated in the source material used here. Look up the current policy on the official ETS GRE pages before you register, since these rules change. Do not rely on what a friend experienced in an earlier admissions cycle.

What should I bring on test day, and what is provided?

Test-day rules, identification requirements, and what calculators or scratch materials are permitted differ by subject and by delivery format. This page cannot confirm them. Read the official ETS test-day instructions for your specific subject test shortly before your appointment, and again the day before, so a last-minute rule change does not block your entry.

How long are scores valid, and how are they sent?

Score validity periods and score-reporting options are determined by ETS and are not confirmed by the source material behind this page. Verify the current validity window and sending options on ets.org before you decide when to test, especially if you are applying in a later cycle and need scores to still be reportable.

Is this page an official ETS resource?

No. This is an independent study page written to help you find your bearings; it is not affiliated with, endorsed by, or sponsored by ETS. Use it to plan your preparation, then verify every administrative detail, including dates, fees, format, and scoring, on the official ETS website, which is the only authoritative source.
