How to make a quiz?
A wiki quiz can not replace exams, and it is not meant to do so. The purpose of a wiki quiz is to make self-tests, meaning “cheating” is not meant to be impossible, or even difficult. A wiki quiz is like math examples and the answer page you sometimes get with them. A wiki quiz can be a excellent tool for presenting an exam example, or to make a self-test as preparations before an exam.
