Boss Battles for Quests

I know there have been posts from at least 3 years ago asking about this and eventually quizzes through Google forms has been possible (though still beta).  The quizzes just don't have the same feeling as a battle though.  The battle is visually engaging and provides additional stimulation/interaction that helps "gamify" learning.  I'm sure there are still plenty of people that would find something like this interesting.

Regarding Google forms, can there be a way to apply rewards based on a student's score?  I want to reward those that get good grades vs a pass/fail type system.  Currently I manually add the rewards since there is only the simple "pass" reward applied to all.
