Two quarters (~1 semester) of Calculus is required, so a lot of integration is left out. Discrete Math is part of the CS curriculum, essentially as an introduction to proofs to prepare people for Algorithms [1]. Linear Algebra is a recommended prereq for some classes, but a lot of people don't take it because more fundamental algebra is covered in classes like Analysis.

Both discrete and high school-style calculus are required: http://collegecatalog.uchicago.edu/thecollege/computerscienc...

I assume parent meant "beyond the standard discrete/calc required of any reasonable cs major".
