For my and other ignorant ones' benefit -- Why Yale??

<p>OK, I am wondering, before any argument ensues, what do people mean by undergraduate focus exactly? Is it that class sizes are smaller, faculty-student ratios are very small in general, that professors are more willing to mentor undergraduates (and less likely to ignore them in favor of their graduate students), or what?
I’m guessing people mean the experience of feeling like they actually matter + are cared for in the school. However, I am interested in asking what exactly defines “feeling cared for” in the first place. </p>

<p>I’ve heard time and again that Princeton has a great undergraduate focus, but I’m not sure I know what it means. More to the point, to all the individuals out there who love Yale (or other comparable schools), what makes you think there’s a greater undergraduate focus at Yale (or not) if you think so (or think not)?</p>
