Hi  @charlan ...

I cannot speak for Instructure (I work at a Technical College in Wisconsin), so I'm not sure that I really have an answer for you on that.  I do know that there isn't really any more work being done on Old (current) Quizzes, and that New Quizzes are their focus now.  Could you maybe explain why you would want to use a regular assignment for multiple choice questions instead of using tools that are already available in both Old Quizzes and New Quizzes?  It seems to me that you'd be creating a lot more work for yourself, and creating multiple choice questions in a regular assignment wouldn't be able to be graded by the system in this way.  So, if you could give an example or two, that would be helpful.  I would recommend sticking with what's already available.  Thanks.
