Advanced Human Studies is an AP elective at Royce. So it's not exactly basic American history. And Izzy didn't even need to take it to know that fact about Danny Diesel. It mostly just seemed like a fun class and an easy A. Evey would've taken it if they had been a bit quicker on the draw. It was filled up by the time they tried to add it to their schedule. Although it mostly would've been to hang with Izzy as their interest in other superheroes is still relatively low.
