The GRE (Graduate Record Examination) General Exam is a required test for most American graduate schools except for law schools, which require the GRE). The GRE consists of three multiple-choice sections, Quantitative, Analytical and Verbal, and an essay section called the Writing Assessment, which is taken separately.
Test Format Changes (as of August 2011)
High-scorers typically spend over 40 hours preparing.
Essay Section: The Issue Essay is 30 minutes instead of 45 minutes long.
Verbal Section: Antonyms and Analogies have been replaced with Text completion and Sentence Equivalence to test vocabulary.
Math Section: There is now a calculator. There are a new variety of complex math questions instead of standard multiple choice.
The GRE is now a “modified CAT test.” This means that the first section will be medium difficulty, and the second section will be hard or easy depending on how well you did on the first section.
