Here in the U.S., getting into college requires passing certain tests. For example, those wanting to get into law school must pass the Law School Aptitude Test, a compulsory examination given by most ABA-approved law schools.
For those seeking admission into an MBA program, there is the GMAT or the Graduate Management Admission Test, a computer adaptive standardized test in math and English. As with any other test, preparation is needed to breeze one's way through this exam. The key is to find a good GMAT prep program to help you.
