As a University professor, what I really don't get about this "experiment" is the timings. They report:

> 36 students examined over 9 days > 25 minutes average (range: 9–64)

It appears that they examined only 4hrs each day, one student at a time. This is incredibly inefficient.

In my experience, the greatest benefit of doing something like this would be to be able to run these exams in parallel, while retaining a somewhat impartial grading system.
