Participating in a quiz or examination in a dream can be a form of initiation that prompts you to consider whether or not your beliefs are assisting you in a constructive manner. If you are running late for the test and as a result receive a failing grade, then your own fears are sabotaging your chances of being successful. It is impossible for a person to achieve success in life if they have the mindset that they will fail. The only way to achieve success is to first experience failure. After overcoming a number of challenges, including failing to meet a goal at one point, it is possible to achieve anything. You are being given the opportunity to let go of your previous way of thinking if all of a sudden you find that you have forgotten what the content is about.
The Trickster archetype might also be triggered when a peculiar character questions the protagonist in some way. You are stopped in your tracks by the contradictions in your thought process, which paves the way for you to begin with a new point of view. This quiz will measure what you know, but keep in mind that there are instances when it's preferable not to know so that you can learn.
