The GRE (Graduate Records Examination) is a standardized assessment administered by the Educational Testing Service (ETS) and is required for admission into many graduate schools in the US and Canada. The test is a multiple choice, computer-based exam designed to test your abilities in verbal and quantative reasoning and analytical writing. The General Test can be taken once every 21 days, up to five times within any continuous rolling 12-month period (365 days). Subject Tests for Mathematics, Physics, and Psychology are also available to supplement undergraduate records, recommendation letters, and other qualifications for graduate-level study.
The Graduate Management Admission Test (GMAT) is a computer adaptive test intended for use in admission to a graduate management progra, such as a Master of Business Administration (MBA) program. Owned and operated by the Graduate Management Admission Council (GMAC), the GMAT assesses analytical writing and problem-solving abilities while also addressing data sufficiency, logic, and critical reasoning skills that it believes to be vital to real-world business and management success. The GMAT can be taken up to five times a year but no more than eight times total; attempts must be at least 16 days apart.
