A final exam is a test given at the end of a course to assess what students have learned throughout the semester. It usually covers all the material taught in class, including lectures, readings, and assignments. Final exams can take various forms, such as multiple-choice questions, essays, or practical demonstrations, depending on the subject. Students often prepare for final exams by reviewing their notes, studying with classmates, and practicing past exam questions. Doing well on a final exam can significantly impact a student's overall grade in the course, making it an important milestone in their academic journey.
