Teachers, please take note: some of my quizzes, like this one, for example, ask for an email. If an email is provided, the results will be sent automatically to it. This allows you to grade/check your students' progress. If you haven't got an email for this purpose, I'd suggest creating one for this purpose, and ask the students to provide that email in the quiz.
