<p>Thanks very much for the replies!</p>
<p>I didn’t actually mean that I wanted to major in biology (just an example), but the links were helpful. I hope all the other departments work like that too, or at least similar to it.</p>
<p>I’m glad now; my mom kept trying to deter me from going to UCSD by telling me I could never finish in four years entering undeclared. It’s possible to take the classes for the major before declaring the major though, so it should be okay…</p>
<p>I hope. :S</p>
