Don’t worry, accidents happen. If you accidentally submitted an exam that you have created, you can find it in the Exams tab of your dashboard. If you would like to delete the exam and try again, you can click Archive next to the desired exam to delete the exam and reset the questions to the question bank.
If you accidentally submitted an exam that an instructor sent you, you will need to contact them directly to see if its possible for them to resend it to you or create a makeup exam. BoardVitals, unfortunately, cannot reset or resend you any exams on behalf of your instructors.
