Same for my school, though our discrete might be a bit less basic. I talked to the department head about it, specifically about calculus, and his answer was that in 30+ years of industry experience, getting a CS PhD (from an engineering university), etc. he had never used calculus in programming except as a type of problem to solve. He suggested people looking to go into fields that might require it to do a math or physics minor, but he saw no need to have everyone do it to get the major.
