<p>Yes, you can always go into a grad program different from your undergrad. HOWEVER, you must show the college/department you want to go to that you are a viable candidate. You may/probably have to take some classes which are prerequisites to the grad program that you didn’t have in your undergrad. You should probably research the particular grad program you are interested in and review their prerequisiets (ie. look at the grad catalog). Taking them in advance of your applying makes you a more attractive candidate and gets them out of the way before the real fun begins.</p>
