COURSE OVERVIEW

GRE

The Graduate Record Examination (GRE) is a 3 hour and 45 minutes, multiple-choice, multi-stage test required by most graduate schools. The GRE is conducted by Educational Testing Service (ETS) and oversees GRE tests, services and research and establishes all policies for the GRE Program.
Schools differ in how they use your GRE score. Some consider it very important, while others view it as a formality. We recommend asking your prospective programs — most will be quite willing to tell you what part the test plays in their admissions decisions.
The GRE has three sections: Verbal Reasoning, Quantitative Reasoning, and Analytical Writing. Verbal Reasoning and Quantitative Reasoning are both multiple choice and are both scored from 130-170 in one-point increments.

However, Analytical Writing, the essay section, is scored from 0-6 in half-point increments. So there are 13 possible scores on that section, and the score range is 0-6.
The GRE Subject Tests, test your knowledge of a particular subject like chemistry or literature. Not every school requires a GRE subject test, but many of the most competitive programs do. ETS offers the tests three times a year.
