One of my buddies attended MIT for his PhD and he didn’t break a sweat in his core curriculum and made perfect grades in his coursework. My buddies who attended lower ranked schools (top 10) had similar stories to share. That being said, doing original research is hard and that’s when things get challenging. The faculty in US engineering programs (top 10) is outstanding. The honors for science goes to European countries. Folks from the Russian block are stellar in pure math— no other nation comes close.
Regret to inform you that I can't deliver. It's been more than a decade and all my emails around the time seem to confirmations of "sending" the score, but no scores themselves...

Look at top 500 universities in the world today and I am sure at least 250 of them will be American.
