Describe the bug
A clear and concise description of what what you were trying to accomplish and what went wrong. Vague statements like X does not work are not helpful. Imagine if one of your students sent you an email that said, "My program doesn't work, whats wrong with it?" Could you help them with only that to go on?
LaTeX does not render in the midterm exam preview. It DOES render when I preview the individual exercise.

Javascript Errors
Many many errors can be quickly diagnosed from the Javascript Console error log. On Chrome this is View --> Developer --> Javascript Console, on Safari ⌥⌘i or Develop --> Show Web Inspector on Firefox Tools --> Web Developer --> Toggle Tools

Reproduce the issue in the Midterm exam preview for the HTTLACS or Pretext course, then compare it with the individual exercise preview where LaTeX renders correctly. Check the browser JavaScript console for errors while loading both previews; the work is done when LaTeX renders in the timed exam preview as it does in the individual exercise preview.
