I'm doing a quiz consisting of three categories. The categories have four questions each. I want the user to be able pick any category they want but I still want to make sure that each category is completed by the end of the course. (The user wont have to answer the questions correctly to complete a category)
When a category is completed the user gets sent back to the first slide (the one with three green boxes) so that the user can pick another category.
I'm looking for a solution where maybe a button appears on the "green box slide" when the user has completed all of the categories? Or is there a better solution?
