That isn't even an elite school thing. That's an any school in the top 100 engineering/math/physics/CompSci thing. Mine was ~50ish and the vast majority of people in the program had at least one semesters worth of AP Calculus credits. Linear algebra was a first or second semester course if you followed the default recommended degree plan. That was only about 10 years ago, and other schools I considered all had similar looking degree plans.

I'm inclined to think the concern (that we will run out of supply of people that can do math or something) is overblown. There are plenty of underemployed engineering and science students that took more advanced mathematics classes than the CS kids.
