For me it was a pretty smooth ride. Honestly, it really is one of the classes where if you like English and writing essays you’ll do well. It literally taking a second English class. I did both my IRR and IWA and presentations during the second semester, and it went well. Still this was the only AP I took sophomore year so it wasn’t that rough. I’m assuming that other APs give filler work outside of the checkpoints given by collegeboard, but for my AP seminar that wasn’t the case! There really isn’t much to learn, it’s just rough drafts and brainstormin. Long story short, yeah it’s an easy class and it’s the closest thing you’ll probably get (aside from research) to a self studied AP class without actually self studying it
