All About GRE Subject Tests in 2025

In the evolving landscape of graduate school admissions, standardized tests like the GRE continue to play a significant role. While many institutions are becoming flexible with test requirements, GRE Subject Tests remain a powerful tool for applicants looking to showcase their academic strengths in specific disciplines.

Whether you're applying for a PhD in Physics, a research-driven Psychology program, or a quantitative-heavy MS in Mathematics, these subject tests can set you apart in a competitive pool.

In this guide, we’ll explore the latest updates for 2025, including available subjects, detailed syllabus breakdowns, score trends, and how these tests impact your admissions journey.

01. What are GRE Subject Tests?

The Graduate Record Examinations (GRE) Subject Tests are specialized exams administered by ETS (Educational Testing Service) to evaluate a candidate’s expertise in a specific field.

Unlike the GRE General Test, which assesses overall academic readiness through Verbal Reasoning, Quantitative Reasoning, and Analytical Writing, the GRE Subject Tests dive deeper into subject-specific proficiency.

Purpose

These tests are primarily used by graduate schools to:

  • Evaluate in-depth knowledge in a discipline
  • Differentiate applicants for research-intensive or specialized programs
  • Guide course placements or waive prerequisite coursework
