Not sure this have ever happened to me before, but I sure wish it had.
In a video posted to Instagram stories, user @the_mi_amor explains how her teacher puts audio questions on the online exams with an example of how the teacher does it.
Then shows another question where there is basically no audio the entire time and then a clearly audible fart sound at the end of it.
It was an impressive fart if you ask me. The teacher definitely understood the assignment.
I bet she wanted to see if her students were paying attention. It certainly got my attention!
