<p>“and do not need to choose or declare your major till the end of your sophomore year.”</p>
<p>I’ll add that this commonly doesn’t happen. Students will wait until junior year to declare, though the registrar will get a bit mad at you if you haven’t declared by the end of the first quarter of your junior year. And of course, you can change your major later on (it’s mostly a matter of dropping it on Axess and adding another).</p>
