The reader of this essay is expected to be familiar with the webCT-1.2 tutorial . The feedback is provided to students automatically, according to chosen answers, but performances are not graded. Informal self-testing drills should not be confused with formal quizzes which are graded.

A single quiz may contain elements of more than one type.
