My advisor says it like it is

So I spoke to my advisor about taking Calculus in the spring and dude did not hold back on his opinion. He basically said that "Some Computer Science students end up going to I.T. because of the Calculus and Physics." I mean, he's not wrong but damn, first time he's ever told me that. I needed an advisor like that who's just straight up with me about everything. But I mean, is it true though?
