Calculus is critical. One of the few moments in university was learning how so much was actually Calculus. Whether it was physics, chemistry, etc, the formulas I was given ften had a calculus version. It helped me open up to taking math and stats courses I never would have as a comp sci student, which in turn gave me a different perspective than just taking cs courses alone.
