Oh yeah, this is very interesting too. Personally, I really cannot fully participate in each and every class when I'm taking 5 classes a quarter. I can only mange to do this by intensely focusing (and going to class) on 2-3 courses, and then practically skipping all the lectures for the other courses (but still managing to do quality work in them relative to the rest of the class)
Smith College is considering trying to make itself more attractive to smart students on the autism spectrum. I would be grateful for suggestions on how to do this from autistics who read LessWrong. You can write comments here or if you wish to remain anonymous send them to me at Jdmiller@Smith.edu
