The local college has free tuition for 'non-conventional' (AKA old) students. I think I did more homework the first semester than I did combined during my first 12 years in public education. But the upside is that it comes back pretty quickly.
I still think a graphing calculator isn't needed, or even really useful for basic calculus. But it was required..........and cost me half a grade point learning how to use a TI-89.
