Survey questions don't have right/wrong answers, so there's nothing to score. In that case, the Results slide is used to submit the answers to the LMS/LRS. The LMS/LRS determines how to pull a report on those answers. But the answers aren't stored in variables you can access.
To accomplish your goal, you could use custom variables to track the answers. As for emailing them to the user, well, that would require JavaScript. Sorry, I can't help you with that. However, you could search the community to see what's already out there. Or perhaps one of the JS experts will chime in.
