Did something not too dissimilar for storing test answer randomization and answers in an older elearning standard. I had limited space, so for each screen, I used a single byte to store the state of if it was seen, the answer selected and order of answers. The intent was to randomize answer order on display to make it harder to pass an answer key around. This is more impressive though... Cannot even imagine the effort it took.
