<p>If I got accepted to my first choice college and I decide I want to switch to Pre-Business because I want to eventually be in Haas, what should I do? When? And how hard is it?</p>
<p>You don't have to transfer colleges or anything. All you have to do is take the Haas prereqs and apply around 2nd semester sophomore year. If you get in, then you are in Haas and you major in Business Administration. If not, you stay in your current college and major in something else. The acceptance rate for Haas is 60%, but keep in mind this is all Berkeley students so the competition isn't easy.</p>
