<p>You can take graduate level physics classes. I know of a kid who is taking both undergrad quantum and grad quantum currently. Also, note that the timeschedules link is not completely fleshed out. For example, few if any graduate courses are listed yet.</p>
<p>Also, you will find that many other schools list every course they have offered in the past 5/10 years in their course catalog, even though it was only offered once and may never be offered again. UChicago will not do that. Physics is one of our strongest disciplines (I believe we have over 20 Nobels in Physics), and you will find plenty of courses to take (consider real analysis, complex analysis, functional analysis, ODEs, PDEs, etc. in the math dept.)</p>
<p>Edit: Many physics undergrads come here for the research opps. A physics major friend of mine has not done terribly well (gpa 3.3-3.4 I think) in classes, but has co-authored several papers, and will get to go to her pick of physics phd programs (mit, caltech, etc.). These opps. are available to anybody who is motivated enough to take advantage of them; note that my friend often works 15+ hrs/wk in the lab.</p>
