An IMO legitimate question about our #rexams pkg was closed before I could answer it. Maybe some of you want to help reopen it? Thanks in advance!

Can anyone here share experiences from their #university (preferably in ) about using #moodle for regular large summative exams?

Some German #rexams users are looking advice on pros/cons/caveats/etc.

If your institution uses #Blackboard, please support this request to enable #MathJax. This will improve math display for everybody, especially those using #rexams.

(First sign up with institution e-mail, then "vote the idea".)

PSA for users of #rexams and #moodle.

You can assign partial credits to numeric answers from guessing tasks. For example, when the given answer is reasonably close to the true answer - just not close enough to be fully correct.

If this is of broader interest I would also consider including the function in R/exams directly...
