<p>Berkeley has enormous biology departments with a very wide range of offerings.</p>

<p>However, biology also has a huge number of students (probably about 900 per year), so expect to see some very large classes, particularly in lower division prerequisites.</p>
<p>On the other hand, some of USC’s biology courses are also large (as in ~200 students), presumably reflecting the popularity of biology.</p>
<p>Berkeley and USC list capacity and enrollment in their on-line schedules. Northwestern does not.</p>
