How Exams are different from Assignments
Exams have time limits - usually 50 minutes. Assignments do not have time limits. You are allowed only one attempt on Exams. Once you submit the Exam, you cannot open it again and change your answers. On Assignments, you can re-open the Assignment and make another attempt any time before the assignment is graded. On exams, you may not seek or accept help from any one (except the instructor).
