Why is the time limit of most exams 3 hours?
Can you tell me why the time limit of most exams is usually 3 hours?
The three-hour time limit for most exams is based on research that shows that the average human brain can concentrate effectively for around two to three hours. After that, it becomes difficult for people to sustain their level of focus, and their cognitive abilities start to decline. Therefore, a three-hour time limit is usually considered optimal for most exams.
