The Graduate Record Examinations (GRE) is a test which is an admissions requirement for many graduate schools in the United States of America, in other English-speaking countries, and for English-taught graduate and business programs world-wide. GRE has been invented and is being run by organization called Educational Testing Service (ETS)  in 1949.GRE measure candidate in area of  verbal reasoning, quantitative reasoning, analytical writing, and critical thinking skills. The GRE General Test is offered as a computer-based exam administered at Prometric testing centers.

In the graduate school admissions process, the level of emphasis that is placed upon GRE scores varies widely between schools and between departments within schools. The importance of a GRE score can range from being a mere admission formality to an important selection factor.

The GRE was significantly overhauled in August 2011, resulting in an exam that is not adaptive on a question-by-question basis, but rather by section, so that the performance on the first verbal and math sections determine the difficulty of the second sections presented. Overall, the test retained the sections and many of the question types from its predecessor, but the scoring scale was changed to a 130 to 170 scale (from a 200 to 800 scale).

The cost to take the test varies between US$130 and $210, depending on the country in which it is taken, although ETS will reduce the fee under certain circumstances. They also promote financial aid to those GRE applicants who prove economic hardship. ETS does not release scores that are older than 5 years, although graduate program policies on the acceptance of scores older than 5 years will vary.
