<p>“Undecided” is probably the norm, not the exception, among students entering most arts & science programs (at LACs and universities alike). So, trying to identify schools that “love undecideds” is unlikely to get you very far in narrowing down your choices. Most students change majors. </p>
<p>Most arts & science majors do not require you to start taking prerequisites in earnest from the first semester. The exceptions would include areas like foreign languages, which build cumulatively on a foundation of specific skills that take years to develop. Pre-med, too, requires you to take more or less specific courses, some of which must be taken in sequence. However, as long as you cover those courses, you can major in nearly anything. Pre law is even more flexible.</p>
