Graduate Record Examination or GRE is a standardized test that is an admission 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 primarily focuses 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 selected qualified testing centers; however, paper-based exams are offered in areas of the world that lack the technological requirements. In the graduate school admissions process, the level of emphasis, that is placed upon GRE scores varies widely between schools and even departments within schools. The importance of a GRE score can range from being an important selection factor to being a mere admission formality.
