CLEP (College Level Examination Program) exams are a group of standardized tests that assess college-level knowledge in 36 subjects and provide a mechanism for earning college credits without having to take college courses. You should take these tests if you wish to demonstrate a college-level proficiency in a subject on cases where you did not go to college or did not go to a United States college.
The results of the CLEP exams are available (A) immediately.
