These intro courses have always had all the answers all over the internet already far before AI showed up, at least at my university they did.

I took a political science class in 2018 that had questions the professor wrote in 2010.

And he often asked the questions to be answered before we got them in the class. So sometimes I'd go "what the fuck is he referencing? This wasn't covered. It's not in my notes."

And then I'd just check the question and someone already had the answers up from 2014.
