The Graduate Record Examination or GRE is a standardized test that is an admissions requirement for many graduate schools principally in the United States, but also in other English speaking countries. Created and administered by the Educational Testing Service (or ETS), the exam is primarily focused on testing abstract thinking skills in the areas of math, vocabulary, and analytical writing. The GRE is typically a computer-based exam that is administered by select qualified testing centers; however, paper-based exams are offered in areas of the world that lack the technological requirements.
