Changing Majors AT UCDAVIS

<p>Hey i was just wondering if there are any uc davis students out there who can tell me how hard it is to switch majors once at uc davis. how hard is it to switch from soemthing like mech. engineering to like bio tech. what do i have to do in order to switch? is it easy or really difficult to get a major like biotech? is there a certain GPA i need in order to switch?</p>
