<p>Actually, you choose at the end of 2nd term freshman year. But you’re definitely free to change after that, although by a year later it’s kind of late, I’d imagine.</p>
<p>A lot of people change majors from what they thought they would be coming in (this is true in general). If you’re interested in things like geology and astronomy, taking a menu class during 3rd term of freshman year may be particularly eye-opening.</p>
<p>I’ve heard that undergrad major is not actually that important. But I’m just a sophomore, so I’ll let other people answer that =P</p>
