Can Stanford undergrads coterm in MS&E with any undergraduate major?

Yes, I knew people who cotermed in MS&E (and other masters programs) with a different undergrad major. I think you just need to make sure you fulfill whatever prereq courses they ask for but my knowledge is old at this point. I imagine you’d be fine going from any engineering major to MS&E, but if you were an English major who happened to take a bunch of math and physics that would probably work too.
