<p>I think we can agree that there is a difference between a professor giving a lecture to a class of 50, 100, or more, then breaking down into grad student taught sections of 25 at a university and a class that consists entirely of a professor and 20 students, more likely to be found at an LAC.</p>
<br>
<p>I agree that there's a difference between a lecture class and a seminar, but the number of seminars is not a good way to differentiate universities and LACs. Look at the USNews stats for % of classes under 20 -- they're virtually identical (low 70's) for HYP and AWS. It was my personal experience that a lecture course is a lecture course, whether there are 50 fellow students or 150. Your mileage may vary.</p>

<p>When you need letters of recommendation, professors are useful and grad students are useless.</p>
<br>
<p>If for some reason you need a letter of recommendation from a professor in a field where you've only had large lectures (this would be quite unusual at any Ivy), the TA composes the letter and the professor signs it. I've advised many clients who were graduates of large public universities and did this; they never had trouble getting the professors to go along.</p>
<p>At any rate, the OP was asking specifically about Columbia, Stanford, and the like, and this is a non-issue at those schools, because everyone takes many small classes in addition to large ones. If you look at how HYP students do as far as Rhodes scholarships and other prizes that are heavily dependent on multiple recommendations, it's clear that they aren't suffering from poor recs relative to LAC students.</p>

<p>If you respond better to a more cozy environment, then a place like Harvard would not be appealing.</p>
<br>
<p>I agree completely. Note that I said that you can get as much professor contact there as you WANT -- if your goal is to fly under the radar, you can, but professorial contact is there for the taking if you WANT it. I certainly never claimed, and never would, that Harvard is a place of tremendous professorial hand-holding, or the ideal school for a shrinking violet. But that's not what the OP asked about in this thread; there are many "fit" threads devoted to that topic. The OP specifically stated that s/he was NOT asking about "face to face" interaction or "lunch with" professors, but about whether the famous names actually teach undergrads. At every school s/he mentioned, the answer is, they do.</p>
