I'd say our posts are completely opposite in thinking. You think most texts and instructors aren't dipshits, I think they are. You think Calculus is hard to learn, I think it's easy.
I think that on HN some people do not understand what the academic experience is like for the majority of students and you've provided confirmation of that.
I know what the academic experience is like for the majority of students, it was me my first year of college. I realized that almost all teachers are dogshit after that and only attended class when it was required, studying on my own. Most people don't come to that realization until it's too late, though.
