@smsk As somebody working in Cyber Security filed (and having PhD, and doing Physics, and Math, and lost of scientific coding, and publishing papers in my past lives) I am a bit puzzled by the statement that Calculus is not needed for CS major. May be it is possible to navigate the graduation requirements without taking Calculus, but it will be hard to navigate the profession without knowing one. Remember that Computer Science is not about coding all the time. One has to understand the algorithms, and doing so is not fully possible without being fluent in Calculus.
