School exams are assessments that students take to measure their knowledge and understanding of a subject. The three most common types of school exams are tests, ORAL exams, and PSATs. Tests are written examinations that assess a student's knowledge and understanding of a subject. ORAL exams are verbal examinations that assess a student's ability to communicate their knowledge and understanding of a subject. PSATs are standardized tests that measure a student's academic readiness for college.
