I never pay attention to my guest quiz plays, but since it was mentioned, I took a peek. It seems to me that someone was given homework... To play my "Microscope parts and lenses" quiz. I saw tons of plays yesterday during a short period of time, and then nothing, and then again a ton appeared at the same time again, about 8 hours later. Seems to me a bunch of the class decided to take it before bed, and others procrastinated and did it just before they had to leave.
Teacher won't be happy; they didn't score well. Haha.
