<p>Personally, I've never been able to figure out what the heck people mean by "undergrad focus," but the phrase does seem to be trotted out on these boards with some regularity. As best as I can tell, it typically seems to be used by Princeton supporters as a means of claiming that the undergrad experience at Princeton is better than at Harvard and Yale, and by Yale supporters as a means of claiming that the undergrad experience at Yale is better than at Harvard. If you mean something different, then I apologize for jumping to conclusions (but then again, if you mean something different, I have no clue what you mean).</p>
