Can I have two results pages that use the same question bank and question draw?

Joe is right - but - I have done something like you are asking before . . . not letting them take the questions multiple times, but using two different results . . . but it can sometimes act a little wonky because that is not a normal use case.  The main thing is to make sure they are not both final assessment results.  Change one of them to a knowledge check for example and you should be able to make it work.  Once you build the results slide, if you go back in and edit them, they will usually deselect them in the other Result, so you have to check each before you publish.
