The GRE is a standardized test that is mandatory for most graduate schools in the United States. It is governed by Educational Testing Service (ETS), a non-profit organization, and aims to assess skills in quantitative reasoning, analytical writing, critical thinking, and verbal reasoning that have been developed over a period of time and are not specific to any field of study. The test is administered through a computer-based system at Prometric testing centers globally. However, the importance placed on GRE scores during the graduate school admissions process can vary greatly between schools and departments, ranging from a mere formality to a significant selection criterion.
There are two types of GRE tests available: the GRE General Test, which measures skills required in today’s demanding graduate and business school programs, and the GRE Subject Test, which assesses knowledge in a specific field of study, allowing students to showcase their proficiency and differentiate themselves from other applicants.
