switching major?

<p>so I got into HSS as a history major. But I might want to switch into a statistics or go into MCS (which I applied as a Physics major and got waitlisted) or even like CIT or Tepper. How hard is it to change majors within the specific school or change schools within CMU?</p>

<p>is there anything i can do to get off the waitlist for mcs? what if i want to go to cit and do like biomedical engineering. is the only way to show that I’m capable of taking these courses by taking classes related to the topic?</p>
