<p>Usually, if you get rejected from HAAS, you major in Economics-- if business is still the route you're trying to go. (Not that economics is easier or anything, it's just the closest thing you're going to get to business).</p>
<p>Also, the class requirements for HAAS aren't solely all things realted to business-- there's some English, math, etc. And those breadth classes, too. So don't be too worried about not finding a major.</p>
