GRE Subject Tests: Mathematics, Physics and Psychology Guide for Graduate Admission
GRE Subject Tests are specialized achievement tests for students who want to show strong knowledge in a specific academic field. Unlike the GRE General Test, which measures general verbal, quantitative and writing skills, GRE Subject Tests measure your depth of knowledge in Mathematics, Physics or Psychology. This guide explains who should take a Subject Test, how the test works, test dates, scoring, preparation strategy and how MKS Education can support Nepal students.
GRE Subject Test Quick Facts
Subject Tests are useful when your target graduate program wants strong evidence of subject-level knowledge.
Mathematics, Physics and Psychology.
Total score is reported on a 200–990 scale.
Available in September, October and April windows.
What Are GRE Subject Tests?
GRE Subject Tests are designed to measure knowledge and skill in a particular academic discipline. They are intended for students who have an undergraduate major or strong background in Mathematics, Physics or Psychology. Graduate programs may use Subject Test scores to supplement your academic transcripts, recommendation letters, statement of purpose, research profile and other application materials.
For Nepal students, GRE Subject Tests are not required for every university or every program. Some programs may require them, some may recommend them, and many may not ask for them at all. Therefore, before preparing or registering, students should first check the official requirement of each target university and department.
GRE Subject Test is different from GRE General Test
The GRE General Test measures broad skills such as Verbal Reasoning, Quantitative Reasoning and Analytical Writing. A GRE Subject Test measures specialized knowledge in one field. Students applying to research-heavy graduate programs may sometimes use Subject Test scores to strengthen their academic profile.
Do not take it unless it supports your application
A Subject Test requires serious preparation. If your target program does not require or value it, your time may be better spent on GRE General Test, IELTS/TOEFL, statement of purpose, research profile or application documents.
GRE Subject Tests: Mathematics, Physics and Psychology
The current GRE Subject Tests are offered in three disciplines. Each test is designed for students with a strong undergraduate background in that subject.
| Subject Test | Test Time | Question Style | Main Content Areas | Best For |
|---|---|---|---|---|
| GRE Mathematics Subject Test | 2 hours 50 minutes | Approximately 66 multiple-choice questions | Calculus about 50%, Algebra about 25%, Additional Topics about 25% | Students applying for Mathematics, Statistics, Quantitative, Theoretical or related graduate programs. |
| GRE Physics Subject Test | 2 hours | Approximately 70 five-choice questions | Fundamental undergraduate physics topics, graphs, diagrams, data and physical situations | Students applying for Physics, Applied Physics, Astronomy, Engineering Physics or related research programs. |
| GRE Psychology Subject Test | 2 hours | Multiple-choice questions based on psychology content areas | Core undergraduate psychology knowledge and content-area performance | Students applying for Psychology, Counseling, Cognitive Science, Behavioral Science or related programs. |
GRE Subject Test Dates and Registration Windows
GRE Subject Tests are not available every day like the GRE General Test. ETS offers them in selected testing windows. For the 2025–26 testing year, the worldwide windows are listed below.
First testing window
Suitable for students applying to early graduate deadlines or those who want scores ready before major application season.
Second testing window
Useful for students who need more preparation time after September but still want scores before many graduate deadlines.
Spring testing window
Useful for students preparing for later deadlines, future intakes or profile strengthening before the next admission cycle.
GRE Subject Test Scores and Score Reporting
Every GRE Subject Test gives a total scaled score from 200 to 990 in 10-point increments. Physics and Psychology tests also report percent-correct subscores for content areas. Scores are reportable for five years from the test date.
Total scaled score
The number of correct answers is converted into a scaled score so scores from different test editions can be compared fairly.
Percent-correct subscores
Physics and Psychology tests report content-area percent-correct scores on a 0–100 scale.
Five-year validity
GRE scores are reportable for five years. Plan your test date according to your admission timeline.
Should Nepal Students Take a GRE Subject Test?
A GRE Subject Test can be useful, but it is not automatically necessary for every applicant. Use the table below to decide whether it fits your admission plan.
| Student Situation | Should You Consider a Subject Test? | Reason |
|---|---|---|
| Your target department requires it | Yes | If it is required, you must plan preparation and registration early. |
| Your program strongly recommends it | Usually yes | A strong score may support your application, especially for competitive departments. |
| Your undergraduate GPA is strong in the subject | Maybe | A high Subject Test score can reinforce your academic strength. |
| Your GPA is weak but subject knowledge is strong | Maybe | A good score may help demonstrate ability, but it cannot fully replace academic records. |
| Your target program does not ask for it | Not always | Focus first on GRE General Test, English test, SOP, recommendation and application quality. |
| You have very limited preparation time | Be careful | A weak Subject Test score may not help your application. Prepare only if you can perform well. |
How to Prepare for a GRE Subject Test
GRE Subject Test preparation is different from regular class exam preparation. The test checks broad undergraduate-level knowledge, application ability, timing and accuracy.
Check whether the test is required
Before studying, confirm whether your target program requires, recommends or does not consider the GRE Subject Test.
Download official practice materials
ETS provides official practice books for the GRE Subject Tests. Use them to understand question style, content coverage and test difficulty.
Map the syllabus against your undergraduate notes
Compare the test content with your bachelor-level courses. Identify which topics are strong, weak or completely missing.
Revise fundamentals first
Subject Tests reward conceptual clarity. Build strong basics before attempting full-length practice.
Practice under timed conditions
Since there are no separately timed sections, you need to manage the full test timing wisely and avoid spending too long on one question.
Answer every question strategically
ETS states that nothing is subtracted for incorrect answers, so it is better to answer every question rather than leaving blanks.
Review mistakes by topic
After practice tests, classify mistakes by topic, concept, careless error, time pressure and unfamiliar question style.
Preparation Focus by GRE Subject Test
Mathematics Subject Test
Focus strongly on calculus and its applications, then revise algebra, linear algebra, abstract algebra, number theory and additional undergraduate math topics.
Physics Subject Test
Revise fundamental principles, formulas, graphs, diagrams, experimental data and problem-solving across undergraduate physics areas.
Psychology Subject Test
Prepare major psychology content areas, theories, research methods, interpretation of results and core undergraduate psychology concepts.
GRE General Test vs GRE Subject Test
Students often confuse these two tests. They serve different purposes and may be used differently by graduate programs.
| Point | GRE General Test | GRE Subject Test |
|---|---|---|
| Main Purpose | Measures broad graduate-level reasoning skills. | Measures knowledge in a specific academic field. |
| Sections / Subjects | Analytical Writing, Verbal Reasoning and Quantitative Reasoning. | Mathematics, Physics or Psychology. |
| Availability | Available more frequently throughout the year. | Available only in selected testing windows. |
| Best For | Most graduate, business and some law program applicants. | Applicants to programs that require or value subject-level evidence. |
| Preparation Type | Reasoning, vocabulary, writing, quant concepts and test strategy. | Deep undergraduate subject revision and timed application practice. |
