If I choose Pass/Fail, do I have to continue to participate in the course, such as completing tests and homework?

You must complete assignments and quizzes/exams as required in your course syllabus. Please consult with your instructor on what needs to be completed to pass the course.

Taking a course for the Pass/Fail grade only means that at the completion of the course—when the instructor submits a letter grade for what you earned—the letter grade will be converted into either a Pass (Y) or a Fail (Z) on your academic transcript. If you stop participating in the course, you could end up earning a Fail (Z) grade even if you had a passing grade at the time you submitted the request for a Pass/Fail grade.
