Scoring a simulator

Hi Hazel and welcome to the community! I'll second Judy's suggestion—variables and triggers might just do the trick. If you're not familiar with how to use them, this article on triggers and this one that Judy mentioned on variables give good, quick overviews.

In this particular case, one way to use them together would be to make a variable to remember the learner's score on the sim, and then use triggers to adjust that score variable up and down. Each answer could add or subtract points from the score variable, with better answers adding more points. And clicking the Hint button for help could subtract points. You can choose how many points each action is worth when you set up each trigger, so you can really customize this approach however you need to.
