<p>Well, if changing your mind is a concern of your parents, then how about this (and I'll say now that all "facts" are 100% anecdotal):</p>
<ul>
<li>I have a friend at a UC (Irvine) who has had a lot of trouble deciding on a major. She's been through chemistry, dance, political science, criminology, and international relations, to name a few. Her biggest troubles were:</li>
</ul>
<p>(1) Lack of guidance.
(2) Classes filling up so that she didn't get much chance to "experiment."
(3) Intro classes that are capped to upperclassmen. A few of the majors she wanted to try had intro prerequisites, but they were full or unworkable for her entire first two years, and after that, were closed to upperclassmen, effectively shutting her out of the programs.</p>
<p>And she went in to college "knowing" her major (chemistry). But when she changed her mind, the support system for figuring things out and getting back on track was just not as strong as it needed to be.</p>
<ul>
<li>Meanwhile, I came in to Scripps with NO clue what I wanted to do. What I ended up with was:</li>
</ul>
<p>(1) Excellent and personal advising, a totally available career center that hosts events such as "What can I do with a major in _______" and "How to choose a major." There's also a "major fair" at the very beginning of the year (possibly orientation...I don't recall), and the general ed. requirements are designed to allow students to explore a wide variety of subjects (ditto Pitzer's GEs, but the two schools go about it in totally different ways).
(2) Excellent facilities for almost anything I was interested in pursuing, and no huge barriers to what I could or couldn't take. At bigger schools, I had trouble b/c I didn't know if I wanted to do English or engineering, but they required students to apply to the College of Engineering, College of Arts and Letters, etc.
(3) Classes that are generally very easy to get into and professors who are, by and large, Hell bent on making life work for their students.</p>
<p>This isn't at all to suggest that UCs don't care about their students or don't provide great opportunities, but there are barriers and bureaucracy that come along with having to deal with many thousands of students vs. 750-900 of them. Both Scripps and Pitzer will get you out in 4 years, so you should definitely not be stuck paying for another year on account of your indecision (unless you voluntarily take time off). Yes, there are trade-offs...variety of course offerings being one of them. But practically speaking, I've been able to get all of the courses I need/want, and I haven't missed that course in Feminist Russian-Cuban Protest Literature of the 14th Century. Like I said, my own indecision was one of the primary reasons that I chose Scripps over larger schools. It may be counter-intuitive, but in my own experience, it worked out for the best.</p>
<p>Disclaimer: There are definite benefits of UCs, and I very nearly ended up at one myself, so please don't take this post as ANY kind of a knock against big schools. The information is anecdotal, clearly one-sided, and directed specifically towards the OP's mission.</p>
