I think I placed out of the physics prerequisites (everyone was expected to have some physics in high school and we went over that and more in a mechanical engineering statics/dynamics/fluids class we all took at the same time) and QED was a standard first semester sophomore year class in the electrical engineering curriculum, the professor made it a lot of fun though every class I remember him deriving equations for thirty minutes on the overhead projector as he explained things, and it was the largest class I had with fellow electrical engineering majors, there was an advanced calculus/diff eq class and linear algebra class during our freshman year.
