Yeah, lots of schools are only MOn-Thurs and then you have Friday to study all day. I've been working for the last 10 years (AND going to school all that time too, lol) and so it's not that I dont want a 5day week...but, just that if it was only 4 days then that'd cut a significant amount of travel time out for me and I could spend all day Friday studying.
Instead, it'll be 5 days of commuting and classes, plus 2 weekend days of studying.
The last I heard about Summer Institute was from David, that they were awaiting funding for it. It is by invite-only (b/c it's for student they think "need" it) and last year I was invited (probalby b/c of my poor GPA from when I frist went to college 10 years ago) and I wanted to make sure I was invited this year too...since I deferred, they might not have looked at my app. I wrote David ysterday, so we'll see. Let me know if you hear, and I'll do the same.
