I have done many shops that require you to take a quiz. It gets very frustrating with quizzes that have trick questions. I have gone through the test. line by line, with the guidelines and still did not pass. They don't show you which questions you got wrong. The test can be a waste of your time. I did one quiz and failed. The scheduler said, one question is a trick question, no matter how you answer, it's counted as wrong.
I remember another test I took required you to watch a cartoon video. One of the questions on the quiz was "What was the color of Bob's shirt in the video?" They have questions that have nothing to do with the shop. There was one shop I did a long time ago, one of the questions on the shop said "what was the color of the employee's eyes?"
