Hi Linda. I see your site is a MoodleCloud site - have you looked at the Moodle Teaching Basics and Moodle Admin Basics courses available on the site Learn.Moodle.org? They are designed specially for MoodleCloud users and amongst other things, in the Moodle Teaching Basics course you learn how to set up your course and create quizzes.
Note that unfortunately you need to create a new account on the site Learn Moodle.org as it is a separate site from this site and your MoodleCloud site. (You can use the same details fore all three sites, but have to create the three accounts separately.)
