So I have a question that's been bothering me for a while. I'm currently an undergraduate majoring in computer-science. I want to do mechanical engineering in graduate school but since I'm a computer science major in undergraduate, I'm not sure if it will work out. Can you major in M.E in graduate school while you are a computer science major in undergraduate? Am I required to know Calculus 1,2 and possibly 3 to major in M.E in graduate school? How does this work because I'm unsure.
