Frequently asked questions
What is an exam timer?
An exam timer is a large countdown used during quizzes, tests, assessments, and practice exams so students and teachers can see the remaining time clearly.
What exam timer length should I use?
Common choices are 10 minutes for quizzes, 20 minutes for short tests, 45 to 60 minutes for class exams, 90 minutes for extended exams, and 2 hours for mock exams.
Should an exam timer show seconds?
For long exams, minutes are usually calmer. Showing seconds in the final minute can be useful for strict endings, but it may be distracting for some classrooms.
