The Graduate Record Examination (GRE) is conducted all through the year in almost all major countries of the World. The test is administered by an organization called Education Test Services (ETS) based in Princeton, New Jersey in USA. Scores of this test are a mandatory requirement for application to graduate programs (leading to MS or PhD) in most universities in the United States. Some universities are considering GRE scores for admission into the MBA programs. GRE is an online exam that tests a student’s Verbal Reasoning, Quant Reasoning, Critical Thinking and Analytical Writing skills. The scores of GRE are valid for 5 years.
