What Are the Two Types of GRE Exams?

There are two types of GRE exams: the GRE General Test and the GRE Subject Tests. These serve distinct purposes in graduate admissions, and understanding the difference is essential for planning your application strategy.

1. GRE General Test
The GRE General Test is the most commonly required exam for graduate programs across disciplines. It measures general academic skills in three areas:

  • Verbal Reasoning: Reading comprehension and vocabulary in context
  • Quantitative Reasoning: Basic math, algebra, geometry, and data analysis
  • Analytical Writing: Critical thinking and written argumentation

This test is computer-based, adaptive by section, and accepted by most master’s and doctoral programs in the U.S. and internationally. It evaluates your readiness for graduate-level work, regardless of your field of study.

2. GRE Subject Tests
The GRE Subject Tests are discipline-specific exams that assess your knowledge in a particular undergraduate field. Currently offered in six areas:

  • Biology
  • Chemistry
  • Literature in English
  • Mathematics
  • Physics
  • Psychology

These tests are designed for applicants whose academic background aligns closely with their intended graduate program—especially in highly specialized or research-intensive fields. Not all programs require them, and they are offered only a few times per year.

Key Difference Between the Two Types of GRE Exams


The GRE General Test is required by most graduate schools and tests reasoning skills. The GRE Subject Tests are optional, field-specific, and measure content mastery. Many programs do not require either, but if they do, they will specify which one.

Always check your target program’s admissions requirements. Some may require only the GRE General Test, while others—particularly in STEM or humanities research programs—may also ask for the relevant GRE Subject Test.

The two types of GRE exams are the General Test and the Subject Tests. The General Test is universal; the Subject Tests are specialized. Choose wisely based on your academic goals and program expectations.
