When to declare major at Harvard

<p>Hi everyone, My Doughter has been accepted to Harvard. Currently she is interested in physics but also interested in premed. Does she need declare major as a freshman or can she do it later? Any information is appreciated.</p>

<p>You don't officially declare until the end of first semester sophomore year, and can change it at any time if you're able to fit in the classes to graduate on time.</p>
