I would like to suggest that an explanation of the correct answer be shown after each quiz question. Sometimes the question is related to a topic covered in the lesson, but the question itself wasn't really covered. Since the quiz can be retaken endlessly, instead of guessing over and over to find the right answer and then not really knowing why it's the correct answer, it would be nice to just get the correct answer right away to commit to memory.
This would also give another place to add extra details that were left out of the lesson for brevity or that just didn't merit being explicitly discussed in the lesson. Maybe even links to further reading on a topic. I have been going over the CORE fundamentals which discuss theory a bit more than advanced lessons, but even if the question is what key do you press for a certain tool, it would be nice to have a quick explanation of the tool and then maybe a link to the blender docs page to read more about that tools capabilities.
It's a great idea. I'll link Kent who's the one that can make the call to make such thing happen. He also likes Lord of The Rings, so we'll play a little more with the fact that you look like Sam Wise in your picture. It can only help our odds. Thanks for the feedback man, it's a good one.
