Quiz Form Giving Incorrect Grades

I'm using the quiz form app for several of my forms. Recently I've been having people report that no matter what answers they choose, they are getting a really low score or, in some cases, a 0. I'm 99% sure it has to do with people taking one quiz then going to a different quiz form on the same computer. I had one person clear their cache on the computer and that resolved the problem.

Is there a way to avoid having to clear the cache when using multiple forms for quizzes?

It could probably be a browser cache issue at their end. That is something we cannot control from our end.

I have additionally cleared your form cache too.

Please check and let us know.
