This lesson is going way too fast...
This lesson is going way too fast without explaining most of the actions you do, you click through and through but nothing is really conveyed. It appears to me it you had a hard time explaining this part of the fundamentals and just went for the accomplishing methodology. I've no analogy to go by in relating what most modifiers do and why enabling & disabling some settings you perform works and others don't. As of now I won't be able to complete the quiz.
I think you should redo this lesson and make it longer for the sake of a more comprehensive and pragmatic approach.
But if you planned to have this lesson slightly incoherent you should instead focus on showing baking but with more demonstration and explain what the use for it is.
