The particular version of linear algebra I took was taken after differential equations, and generally considered the hardest course in the undergraduate curriculum, reserved for EE and physics majors only. In the case of us physics majors, it was a pre-req for thermal physics (statistical mechanics), and due to timing, there was only one semester you could take it.
