As we have been creating questions with the new parameter system, we noticed that we were often seeing issues that were caused by a parameter value repeating. For example, if we created the following parameters…

$p=range(1,10)
$q=range(1,10)

We usually wanted the variability but did NOT want the two parameters to be the same value.

We have now added a No Repeats option to the parameter screen to address this issue. No Repeats is on by default and just prevents $p and $q from being assigned the same value. It has greatly simplified the creation of many questions.
