Hello, I am a middle age graduate student at large at the University of Chicago. Economics and Public Policy are my interests and I'd welcome input on the following. My undergraduate degree only required math through calculus I. I received good grades but was not required to complete higher level calculus. Here is my question. I can take calculus at less expensive universities in Chicagoland, such as Univesity of Illinois Chicago or Depaul. I'd prefer to spend my tuition dollars at the University of Chicago on graduate level courses in the humanities (I received a A- in History of Technology in America this quarter). Would good grades (A,A-) in calculus at the lower ranked schools be looked down on in an application to a top tier Econ School? I'd welcome any feedback.
