I had this happen unintentionally in my sophomore year (computer engineering).
In 3 different classes (MechE, DiffEQ, and circuits) we happened to be going over very similar material from different angles (under/over/critically-damped systems).
I learned those concepts pretty well, with less effort than other quarters.
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
