The tl;dr I got was that high school didn't adequately prepare students for college. Just to have h.s. kids enthusiastic (as someone else mentions in the comments here, high on dopamine) they make things entertaining/easy. While some may argue that college level should have more real world applications, I would argue that high school level should have more hard challenges that fail half the class. Maybe have a class that doesn't count towards your GPA that is super-challenging.
