Rise quiz scoring for multiple response questions

I understand why Articulate doesn't try to give partial credit for multiple-response questions in Rise or in Storyline.

There are so many possible variations, especially related to the responses that shouldn't be selected. For example, someone might want it to add points if the user didn't select a wrong answer. Others might want to subtract points if a user does select a wrong answer. Or not use the state of the wrong answer at all when figuring the partial credit. 

It could also get tricky if you want all questions in a quiz to be worth a given number of points (for example, 10 points). Then how do you divvy up the 10 points for a given question when there are 3 or 4 responses? 

In Storyline, it is possible to do some custom programming to give partial credit for a multiple-response credit. I posted about that and provided a demo file here: https://community.articulate.com/discussions/articulate-storyline/tip-give-partial-credit-on-multiple-response-questions.

I created the demo because I've seen people ask about this a few times in the Forum. Personally, though, I've never used partial credit for a multiple-response question, and I doubt I ever will.
