Moodle Quiz/Exam Save Frequency
Moodle saves quizzes and exams every minute. That means that the most amount of work you can lose due to a power failure, or internet disconnect is what you had filled in during the last 60 seconds. In practice, this will range from 0-60 seconds of work depending on when the last save occurred.
To navigate to a course you are in, go the LEFT TOP corner and select My Courses: Then select the course you would like.
Alternatively, you may simply scroll down to your course.
