Hehe I don't have a US backup university
Anyways, I've sent my letter to caltech today, they're probably going to get it by the end of the month.. I hope that the "deadline" was for postmarking mail by 20th

Well at least, I don't think they will do anything about the waitlist until they get all of the replies on the 1st of May.. So probably that would be a "real deadline" to send anything..
"do you think people will leave Caltech for something else? maybe MIT, princeton or something?"
well based on previous years statistics, a lot of people will decide to enroll at MIT, Stanford and ... hmm some third college, instead of Caltech. But nobody can tell how many people will actually decide to enroll... That's why they making waiting lists in first place
Hmmm.. that's a very interesting question.. do they actually look only at the new stuff.. i'm not sure if it's a good thing or a bad thing for me if they do hahahha

BTW guys, has any of you tried to contact your counselor? I've sent two emails to the international counselor, and he hasn't replied to any

I'm not sure how to interpret this :/ ..
