<p>Another consideration to look at between a LAC and a university: make sure the LAC has four years' worth of work for you. If you expect to need graduate-level coursese while still in undergrad, check carefully to see what resources are available.</p>
<p>To the original poster: what do you mean by a good math/physics program? I can talk about math at Swarthmore for a bit: I'm taking a first-year seminar in Honors Linear Algebra right now and it's great--only 11 students, great professor, lots of close interaction. But the stuff we're learning here would be the same as what we would learn at Harvard or San Francisco State. One difference might be that we go faster, but that would pretty much be it. A course in Calculus I here would probably be very similar to a Calc I course elsewhere.</p>
<p>I second CountingDown's remark: Look through the course catalogs and make sure that if you decide to take a math class every semester or quarter, that you won't be so advanced that you'll be done early. That doesn't happen to most people, but still...</p>
