<p>How difficult to change majors within a college at CMU? Like right away... If I apply under a statistics major in HSS is it going to be hard to switch into an econ major at HSS like right at the beginning of freshman year?</p>
<p>Also in the commonapp why is Business Administration only available under Tepper? What if I want to major in finance is that available at CMU Tepper? THanks so much!</p>
