Declaring a major?

<p>This is probably too early to worry about it, but I would just like some info about declaring a major? I got accepted into L&S, and I'm intending to apply for Haas in my sophomore year but I would like to declare my major as Economics first. </p>

<p>I've heard that econ is a capped major, so how will that affect my chances? :/ Also, declaring a major still makes me eligible for Haas, right? I read about it somewhere on the Haas website but I figured I should confirm this piece of info.</p>

<p>OT, but is attending CalSo very important or is it just kind of good-to-have-but-not-mandatory? Thanks. :)</p>
