\label{Problem_Editor_Testing_Area}

The problem editor gives you a testing area where you can try your problems
out, with several different randomizations by varying the \textbf{Random
Seed}. If you answer a problem correctly and can no longer enter new answers,
you can get the answer field back by hitting the \textbf{Reset Submissions\index{Reset Submissions}}
button.

Problems also may appear differently after the answer date, or on an exam.
The editor provides dropdown selectors to view problems with such conditions set.
