Boy is a hero

I remember in school we had this test where everyone was given this remote kind of thing and the teacher displayed the questions on the projector. Everyone had to give their answers by pointing their 'remotes' towards the screen and pressing the button of their choice. I think this is referring to something like that.

That's the clicker @shadylady

Some professors have "Clicker Questions" every couple of slides during their lectures, often they only count participation, not the actual answer, so it's not really a test.
