Yes, I figured that, but that still leaves the question of how to tell
students which problems they got wrong without revealing the answers. I
first thought that could simply change maxtries to zero after the exam
component. This would allow students to see their correct answer, and if
the due date was unset, they wouldn't be able to see ant answers to the
wrong problems. But unfortunately, maxtries must be >=1 (Why is this? In
this situation, it would actually be useful to be able to set it to zero.)

This is automatic, right? A new "copy" will always have different seeds,
