<p>Brown’s main focus is on undergraduate education. I really wouldn’t say it’s a large school - it’s primary undergrads, with a small grad/med student population. Courses were 100% taught by professors in my experience, with grad students serving as lead TAs if necessary.</p>
<p>You can look up average class sizes on the Brown website. In general, the big lecture courses (intro sciences, etc) will be larger than at LACs, but the rest of classes will be about the same.</p>
