I had something similar (a lot of math and theoretical classes for the first two or three years), and I remember I was pissed off - I only wanted to write C programs! :D But 20 years later, I really appreciate my CS education. It has all paid off: calculus, statistics, probability theory, theory of computation, discrete math, data structures and algorithms, foundations of NNs, etc. Then later, foundational classes for compilers, OSes, multiprocessor programming, networking, distributed systems, and database theory - I've used it all during different stages of my career.
