If you want more flexibility, like quizzes for topic 1A, 1B, 1C and if you don't get a super high score on A, B opens up, if you don't have a high score on B, C opens and then topic 2 opens when you get a good score on A or B or have done all three, etc, you wouldn't want to combine them.
But you could add links in overall feedback at various levels that take them directly to the next piece or in Boost, I think the next activity links might work that way.
But what I really meant was if you have five sections about personality (just for kicks, we'll go with helpfulness, agreeableness, openness, extroversion and conscientiousness) and we'll pretend that there are five questions on each topic and five on each means you're super friendly and 1 on each means you are super shy and not outgoing at all...you could set up labels (resource) with restrictions on when they display (only display if all 5 quiz results are 5 points [wow! you must be a really amazingly friendly and helpful person!]; only display if all 5 quizzes are 1 point [you're feeling some social anxiety, let's work on that!], only display if...), which would be really complicated to set up and see (for you) but would give very specific student feedback based on results...Maybe someone is super helpful--helpfulness of 5, but extremely shy--extroversion of 1, where the feedback provides ways to be helpful without triggering the shyness or helpful hints to overcome shyness (or helpfulness, depending on the objective--I frequently tell my husband to stop being helpful--particularly when he thinks he is helping but really isn't).
Maybe this is too complicated? But it would work, if you wanted them to get particular feedback for specific results. I don't actually build things with this level of complexity...I just recognize it can be done & how to...
