If you started to take a limited-access quiz or exam and cannot get back in, you must contact your course faculty and/or TA for additional access. The CTL Help team cannot give you additional access to quizzes/exams. Your faculty and/or TA can determine the best course of action when it comes to allowing additional time or access to a quiz.
If you are concerned that your final answers for a quiz/exam were somehow not recorded because of a problem when submitting your final answers, please reach out to your course faculty and/or TA. They can verify your submission of answers.
