Back in the day, I was a TA for four years in grad school because my professor lacked funding for my project. Each year you taught sort of earned you an advancement in the level of labs you had, so for two years I taught the senior lab courses. These were mostly kids going to med school, probably 2/3rds of them.
I had a quiz before we went to the lab and I'd have an extra credit question that had nothing to do with chemistry, it was usually history. I recall once asking when the US Civil War started, I was prepared to give credit for anything within say 5 years. I had answers like 1920 and 1542 and 1608, all over the map.
These were the top students, pretty much, at a university ostensibly in the top five of public schools in the nation. Most of them were "what do I need to do to make an A"? types. I did have one guy who was a TRUMPET major, seriously, one of my best students ever. He said he just liked chemistry.
The responses to similar questions were similarly "lacking" for the most part.
