Exams are an important part of the educational process, and there are several types of exams that students may encounter. Midterms (8 letters) are exams that typically occur halfway through a semester or term, and are used to assess student progress. Orals (5 letters) are exams that involve speaking or presenting in front of an examiner. SATS (4 letters) are standardized tests that are used to measure academic aptitude. FINALS (6 letters) are exams that occur at the end of a semester or term, and are used to determine a student's final grade. Retests (7 letters) are exams that are taken after a student has failed an initial exam, and are used to give the student another chance to demonstrate their knowledge.
