The GRE is a test for students seeking an advanced degree that measures critical thinking, analytical writing skills, quantitative reasoning and verbal reasoning. The test questions are not related to a particular area of study. Instead, the test is designed to provide an overview of a student's general knowledge.
The test is delivered in computer-based or paper-based formats at testing sites across the United States. Students must register online and pay a fee prior to taking the GRE. Students seeking entrance to a graduate program or business school are often encouraged or required to take the GRE as part of the admissions process.
