GRE

GRE stands for the Graduate Records Examination; it is a multiple-choice and standardized test given by the Educational Testing Service. Colleges and Universities use the results of the GRE to help them decide which students to accept to their graduate programs. Therefore it is similar to the well-known SAT test except that the GRE is used for acceptance to graduate instead of undergraduate. The GRE is a computerized test that can be taken at authorized testing centers at virtually any time during the year.
The GRE is intended to test general abilities as opposed to specific knowledge about a topic, although a thorough grasp of less-common vocabulary is beneficial. Many people fault the GRE for failing to test for skills and knowledge that would provide better assurance of success in graduate school; despite the controversy, schools still rely on the GRE because it is one of the few widely-available standardized tests that allow them to compare all applicants on a single metric.
There are several sections of the test namely: Mathematics, Verbal and Writing.
