<p>DRab, by “later career,” I didn’t mean junior/senior year. I meant, “beyond high school.” A friend of mine at Caltech was sure he was going to study physics – and all in the course of the five quarters so far, he switched from physics to engineering to chemistry to finally mathematics.</p>
<p>Chicago (like Caltech) does have a strong core curriculum, and even if Berkeley allows you more flexibility in choosing your classes, Chicago allows a greater flexibility to change your major.</p>
<p>Also, because of the existence of the core curriculum, it is less difficult to double major, if you are considering it.</p>
