I ran across this simple question and answer tool to create quizzes or self-assessments quick and easy. It’s called testmoz found at https://testmoz.com/. Four different question types are available, which cover most of the general self-assessment type of question you can create and still give good feedback with one answer. Your students don’t have to create an account but if you want to keep track of who is taking the quiz, and what their score is, then you would create a passcode to access the quiz. If you’d like to use the test manager, test cloning, or get a list of your tests, for a mere $20 you can have more features. But it works just fine for free!
