The term 'MAJOR TEST' can refer to three different types of tests: a FINAL, a MIDTERM, and an EXAM. A FINAL is a test that is usually taken at the end of a course or semester and is used to determine a student's FINAL grade in the class. A MIDTERM is a test that is usually taken halfway through a course or semester and is used to assess a student's progress in the class. An EXAM is a test that is usually taken at the end of a unit or chapter and is used to evaluate a student's understanding of the material.
