The GRE or Graduate Record Exam is required for admission to most U.S., Canadian, and UK graduate schools. Most students attend graduate business school for pursuing an Master degree. In addition, GRE can also be used for admission to PhD program. The GRE general test does not test specific knowledge in any subject. It measures the ability to respond to questions in limited time. The Graduate Record Examination (GRE) is a multiple-choice exam designed to measure verbal, analytical, and quantitative skills. The GRE General Test, required by most graduate schools, many vet schools, and various other allied health professional schools, is considered to be a good predictor of your success in a graduate program. GRE Subject Tests (in 17 specific areas, e.g. Psychology, Biology, Chemistry) are often required for graduate school (Ph.D.) admission, but not generally for health fields.
