The Graduate Record Examination exists in two fundamentally different forms that serve different purposes within the graduate school admissions process. The GRE General Test is a broad assessment of verbal reasoning, quantitative reasoning, and analytical writing abilities that is accepted by thousands of graduate programmes across virtually every academic discipline. The GRE Subject Tests are specialised examinations that assess deep knowledge in a specific academic field, currently available in subjects including Biology, Chemistry, Literature in English, Mathematics, Physics, and Psychology. These two examination types are not competing alternatives where one replaces the other but rather distinct instruments that measure different things and serve different strategic purposes depending on the programme a candidate is applying to and the academic profile they are presenting to admissions committees.
Many candidates enter the graduate school application process without a clear understanding of whether they need the General Test, a Subject Test, both, or neither, because the requirements vary significantly across institutions, departments, and degree programmes. Some highly competitive programmes in the sciences and humanities require or strongly recommend Subject Test scores as a standard component of every application. Others accept only the General Test. Still others have made both optional in recent years as part of broader changes to graduate admissions practices. Clarifying which examination or combination of examinations is relevant to your specific set of target programmes is the necessary first step before any preparation decisions are made, because investing months of study time in the wrong examination is a costly mistake that no candidate can afford when application deadlines are approaching.
How The General Test Works
The GRE General Test is administered by Educational Testing Service and is available as a computer-delivered examination at testing centres worldwide and as a home edition taken under remote proctoring. The examination measures three broad cognitive abilities that ETS identifies as relevant to academic success across graduate disciplines. The Verbal Reasoning section assesses the ability to analyse and evaluate written material, understand relationships among words and concepts, and apply high-level reading comprehension skills to complex texts drawn from academic writing in the humanities, social sciences, and natural sciences. The Quantitative Reasoning section tests mathematical reasoning and problem-solving using concepts from arithmetic, algebra, geometry, and data analysis at a level appropriate for a rigorous undergraduate education rather than advanced mathematics.
The Analytical Writing section requires candidates to complete two separately timed writing tasks. The first task, called Analyse an Issue, asks candidates to construct a persuasive argument responding to a statement on a topic of general academic interest. The second task, called Analyse an Argument, asks candidates to evaluate the logical soundness of a provided argument and identify its weaknesses. Both tasks are scored on a six-point scale by human raters and an automated scoring system, with the final score representing the average of both evaluations. The total testing time is approximately three hours and forty-five minutes. Scores are reported on section-specific scales: 130 to 170 in one-point increments for both Verbal and Quantitative Reasoning, and zero to six in half-point increments for Analytical Writing. The validity period for GRE General Test scores is five years from the test date, which gives candidates some flexibility in how they time their preparation and applications.
How Subject Tests Are Structured
GRE Subject Tests are paper-delivered examinations administered at official testing centres on specific dates throughout the year, with considerably fewer administration dates available compared to the computer-delivered General Test. Each Subject Test is a focused examination that tests content knowledge and analytical skills specific to a single academic discipline at the level expected of a student who has completed an undergraduate major or its equivalent in that field. The examinations are not designed to be accessible to well-prepared generalists but to reward candidates who have dedicated substantial academic effort to the subject area being tested, typically through several years of rigorous undergraduate coursework supplemented by independent research or graduate-level preparation.
The structure and length of Subject Tests vary by field. The Biology Subject Test covers cellular and molecular biology, organismal biology, and ecology and evolution across approximately 190 questions. The Chemistry Subject Test covers analytical chemistry, inorganic chemistry, organic chemistry, and physical chemistry across approximately 130 questions. The Literature in English Subject Test covers literary analysis and works in English from various periods and traditions across approximately 230 questions. The Mathematics Subject Test covers calculus, algebra, and additional topics from advanced undergraduate mathematics across approximately 66 questions. The Physics Subject Test covers classical mechanics, electromagnetism, quantum mechanics, thermodynamics, and related topics across approximately 100 questions. The Psychology Subject Test covers biological, cognitive, social, developmental, and clinical psychology across approximately 205 questions. Each test is scored on a 200 to 990 scale in ten-point increments, with a sub-score scale available for some subjects.
When General Test Scores Matter
The GRE General Test scores matter most in admissions contexts where the programme is evaluating candidates from diverse academic backgrounds who may not share a common disciplinary training. When an admissions committee reviewing applications to a graduate programme in public policy, education, interdisciplinary studies, or professional degree programmes receives applications from candidates who majored in economics, political science, sociology, literature, and engineering, the General Test provides a common assessment framework that allows the committee to evaluate analytical and reasoning abilities across that diverse applicant pool. The Verbal Reasoning score is particularly relevant for humanities and social science programmes that emphasise writing and textual analysis, while the Quantitative Reasoning score carries more weight in science, engineering, economics, and programmes with significant quantitative methods components.
The analytical writing score is relevant across virtually all graduate programmes because graduate education universally requires students to produce clear, well-reasoned written arguments, and the Analytical Writing score provides a standardised data point about that capability that supplements the writing sample many programmes request separately as part of the application. Some highly selective programmes use GRE General Test scores as an initial screening filter that determines which applications receive full review, which means a score significantly below the average for admitted students at a target programme can prevent an otherwise strong application from receiving the careful consideration it deserves. Understanding the score expectations at each target programme, researching the average GRE scores of recently admitted students, and setting preparation targets accordingly is essential for candidates whose General Test scores will be used in this way.
When Subject Test Scores Help
GRE Subject Test scores provide the most direct benefit in admissions contexts where programmes are evaluating candidates specifically for their mastery of a defined body of disciplinary knowledge. Doctoral programmes in physics, for example, receive applications from candidates with undergraduate degrees from institutions with very different curricular requirements, grading standards, and instructional quality. An undergraduate GPA of 3.8 from a programme with a well-known rigorous curriculum is not directly comparable to a 3.8 from a programme where grade inflation or lighter coursework requirements make high grades more accessible. The Physics Subject Test score provides a standardised measure of what a candidate actually knows about physics regardless of where they studied it, which allows admissions committees to make more confident assessments of preparation for doctoral-level coursework.
Candidates with undergraduate academic records that do not fully reflect their capabilities also benefit substantially from strong Subject Test scores. A candidate who transferred institutions, changed majors partway through undergraduate study, performed inconsistently across semesters for personal reasons, or attended an institution with limited recognition in the graduate admissions community can use a strong Subject Test score to demonstrate subject mastery that the transcript alone might not communicate. International candidates applying to programmes in the United States face similar challenges when admissions committees are unfamiliar with the grading standards and curricular rigour of foreign institutions. A competitive Subject Test score provides objective evidence of academic preparation that transcends the interpretive uncertainty that can attach to transcripts from unfamiliar institutions or educational systems.
programmes Requiring Subject Tests
The programmes most likely to require or strongly recommend GRE Subject Test scores are doctoral programmes in fields where the Subject Test exists and where disciplinary preparation at the undergraduate level is both well-defined and critical to success in graduate study. Physics doctoral programmes at research universities consistently rank among the most frequent requirers of the Physics Subject Test, reflecting the precise and extensive body of knowledge that successful physics doctoral candidates must possess before beginning graduate coursework. Chemistry doctoral programmes similarly value Subject Test scores as a measure of preparedness across the subdisciplines that the test covers. Mathematics doctoral programmes use the Mathematics Subject Test to evaluate candidates whose undergraduate training in advanced mathematics can be difficult to assess from transcripts alone.
In the humanities, doctoral programmes in English literature and comparative literature sometimes require or recommend the Literature in English Subject Test as evidence of broad familiarity with the literary canon and analytical reading skills across historical periods. Psychology doctoral programmes, particularly those with clinical or research emphases, may request Psychology Subject Test scores to evaluate candidates whose undergraduate preparation in psychology covers the range of subfields represented on the examination. The key practical step for any candidate is to research the specific requirements of every target programme by reviewing the programme’s current admissions webpage rather than relying on secondhand information, because Subject Test requirements have changed for many programmes in recent years and the only reliable source of current requirements is the programme itself.
Score Validity And Timing
The timing of GRE examinations relative to application deadlines requires careful planning because both the General Test and Subject Tests have specific score reporting timelines that affect when candidates should register and sit for the examinations. GRE General Test scores are reported to institutions within ten to fifteen days of the test date when delivered by computer, which gives candidates flexibility to take the examination relatively close to application deadlines if necessary. Subject Tests are paper-delivered on specific dates with fewer annual administrations, and scores from these examinations take approximately five weeks to be reported, which means candidates must plan their Subject Test date carefully to ensure scores arrive at institutions before application deadlines.
Score validity for both the General Test and Subject Tests is five years from the test date, which means scores from examinations taken during the final years of undergraduate study remain valid for use in graduate applications for several years after graduation. Candidates who took the GRE during their undergraduate years and are now applying to graduate school should verify whether their scores are still within the validity window before deciding whether retaking is necessary. The ability to send scores from multiple test dates through ETS’s ScoreSelect option means candidates can choose which scores to send to institutions, allowing them to send only their strongest scores if they took the examination multiple times. Understanding ScoreSelect policies and how they interact with individual programme requirements, some of which ask candidates to report all scores rather than selected scores, is an important strategic consideration in planning when and how many times to sit for the examination.
Preparation Time Requirements
The preparation time required for the GRE General Test and GRE Subject Tests differs significantly and should directly inform how candidates plan their application timelines. GRE General Test preparation for a candidate with a solid undergraduate education typically requires two to four months of structured study to reach a competitive score, with candidates starting from lower baselines or targeting scores in the highest percentiles potentially requiring longer preparation periods. The General Test measures skills that develop over years of education rather than a specific curriculum, which means preparation involves sharpening existing abilities rather than learning a defined body of new content, and the improvement achievable in a fixed preparation period is somewhat constrained by the foundational skills developed throughout a candidate’s academic history.
Subject Test preparation has a different character because it requires comprehensive command of a specific disciplinary curriculum. A candidate preparing for the Physics Subject Test needs to demonstrate competency across classical mechanics, electromagnetism, optics, thermodynamics, quantum mechanics, atomic physics, special relativity, and laboratory methods, which represents the content of an entire undergraduate physics major. Preparation that genuinely builds subject mastery across all tested areas typically requires three to six months of dedicated review work using the appropriate undergraduate textbooks, supplemented by extensive practice with official Subject Test material. Candidates who completed their undergraduate coursework in the relevant subject recently will require less preparation time than those whose undergraduate study was several years ago and whose knowledge in specific subfields has faded through disuse. Accounting honestly for both the breadth of the tested curriculum and the current state of your own knowledge when estimating preparation time is essential for setting a realistic examination schedule.
Cost And Registration Considerations
The financial and logistical aspects of GRE registration are practical considerations that candidates need to account for in their application planning. The GRE General Test registration fee is currently 220 dollars in most countries, and the Subject Tests are priced at 150 dollars per examination. Candidates who need to send scores to more than four institutions pay an additional fee per institution beyond the four free score reports included with registration. Taking both the General Test and a Subject Test, sending scores to multiple programmes, and potentially retaking one or both examinations represents a meaningful financial commitment that candidates should budget for explicitly as part of their graduate application expenses.
ETS offers fee reduction certificates for General Test candidates who demonstrate financial need, which reduce the registration fee by fifty percent and include four additional score reports. The fee reduction programme is not available for Subject Tests. Registration for both test types is completed through the ETS website, and candidates should register well in advance of their desired test date because popular testing centre locations and dates fill to capacity quickly. Subject Test registration requires particular early attention because the limited number of annual administration dates means missing a registration deadline can force a candidate to sit for the examination on a later date that may not allow sufficient time for scores to be reported before application deadlines. Identifying the specific administration dates available for your Subject Test, working backward from your earliest application deadline, and registering for the appropriate date several months in advance is the most reliable approach to avoiding logistical complications.
Making The Strategic Choice
The strategic choice between the General Test, a Subject Test, or both ultimately depends on three intersecting factors: the specific requirements of your target programmes, the comparative strength of your academic profile in each tested area, and the return on preparation investment that each examination offers given your available time and resources. For candidates applying to programmes that require both, the choice is made for them and preparation must address both examinations regardless of personal preference. For candidates whose target programmes require only the General Test, the question is whether voluntarily submitting a strong Subject Test score would meaningfully strengthen applications that are otherwise competitive, which depends on how central disciplinary knowledge assessment is to the programme’s admissions evaluation and whether a competitive score is achievable within available preparation time.
Candidates should also consider how their Subject Test score is likely to compare to the pool of applicants at their target programmes before committing to the significant preparation investment a Subject Test requires. Submitting a below-average Subject Test score to a programme where applicants typically submit strong scores can raise concerns about subject mastery rather than demonstrating it, which makes the strategic calculus of optional Subject Test submission more complex than it might initially appear. Consulting with faculty mentors, graduate students in target programmes, and current admissions information from each programme provides the contextual intelligence needed to make genuinely informed decisions about which examinations to prioritise. The goal is not to take every available examination but to take the examinations that will most effectively communicate your preparation and potential to the specific programmes where you want to pursue graduate study.
Conclusion
Building an effective preparation plan for the GRE begins with the diagnostic step of taking a full-length official practice test under realistic conditions to establish a baseline in each tested area. ETS provides free official practice materials for the General Test through the POWERPREP platform, which delivers computer-adaptive practice tests that simulate the actual examination experience with high fidelity. Official Subject Test practice materials are available through the ETS website as downloadable practice books containing retired examination questions that represent the authentic style, difficulty level, and content distribution of the live test. Beginning preparation without an honest baseline assessment leads to misallocation of study time and an inaccurate sense of how much improvement is needed before the examination.
Once baseline scores are established, a preparation plan should allocate study time in proportion to the gap between current performance and target performance in each tested area, with additional attention given to areas where a candidate’s foundational knowledge is weakest. For the General Test, official practice materials supplemented by vocabulary-building resources for Verbal Reasoning and targeted mathematics review for Quantitative Reasoning cover the essential preparation needs for most candidates. For Subject Tests, undergraduate textbooks in the relevant discipline combined with official practice examinations and, where available, specialised preparation guides provide the comprehensive content review that the examinations demand. Setting weekly study goals, tracking progress through periodic timed practice sessions, and building in sufficient time before the examination date to adjust the preparation plan based on what practice results reveal are the habits that distinguish candidates who achieve significant score improvements from those who study extensively without producing the results their effort warrants.
