FYI I've always been discouraged about this. I remember thinking in high school "If I don't go to a T10 UG, I'll never get in anywhere decent for grad school"

But does HYS, for instance, have more prestigious UGs represented? I'm assuming law school make-up is more likely to include top people from decent institutions, not necessarily Princeton or wherever. I'd wager that you might even be screwed over by attending HYP if you're not supreme with your GPA.
