I was just astonished to learn that apparently, my Canvas settings were set so that students cannot see the correct answers after the quiz! :-O That seems like the dumbest thing in the world — you guess “Decorator” for the last question on quiz #5, and know you got it wrong, but never learn what the correct pattern for that box example was (the correct answer for that particular question was Composite, by the way).

Anyways, I never in a million years intended to hide the correct answers from you after you have completed the quiz, and I think I have now configured Canvas properly so you can see them. When you get a chance, you might take a peek at one or two of your old quizzes and verify that you can see the correct answers for any items you may have missed!
