<p>The physics department is smaller than the biology and chemistry departments. Your intro level courses will be about 30 (about 35-40 if you’re on the pre-med physics track: Physics 104/106 instead of the major-track: Physics 107/108). Once you get to upper level courses all your classes will be about 10 or less, depending on the year.</p>
<p>Labs are really small, which I really appreciate about Wellesley. Intro physics labs are maxed at 15-16 if I remember right. Upper level labs run about 6 per lab. You work with a partner for your labs, and you get lots and lots of face time with both your professor and your lab instructor.</p>
