A test is typically a shorter assessment that evaluates a student's understanding of a specific topic or concept. Tests are usually given more frequently throughout a course and may cover a smaller amount of material.
An exam, on the other hand, is a more comprehensive assessment that evaluates a student's knowledge and understanding of a larger portion of the course material. Exams are usually given at the end of a course or semester and cover a wider range of topics.
In summary, tests are smaller assessments given more frequently throughout a course, while exams are larger assessments given at the end of a course or semester.
