Oh c'mon. As much as I like and respect GWB, he is a Yalie too. Yale is just another check in the block for our political elite. A Yale sheepskin is worth 'merde' except to another Yalie. Of course, they run our government, so ....
I'm talking Yale graduate school. This is an entirely different from undergrad.
Just imagine having to past a test in French or German, Latin or Greek, plus one other foreign or ancient language of your choice in the first week.
Or in a single one-semester course, having to read all the novels of Jane Austen and Dickens, plus several biographies and critical tomes on on each one, and producing a ten-page paper every week to prove you're doing it. That's only one of the four courses you're taking.
Believe me, what the undergraduates do is piffle, but the grad school is quite tough.
