i totally agree with you, snivellus! ED was great. i knew before all of my friends, which gave me a little bit of a seniority complex, because it was like i was already in college and other kids didn't have acceptances yet.

me and the other EDers at my HS (to different schools) would feel so chill as everyone else stressed. i could relax and concentrate on yearbook, which was getting down to serious business right after winter holiday, which was also nice.
also, you meet fellow EDers on facebook in like, december, so you already have that sense of community/"OMG, we're practically there already!"
so yeah, definitely recommend it if it's financially doable. (same with my, snivellus, i ignored that little bit as well, but i didn't really matter in the end, because barnard gives the same financial for ED as RD.)
oh, and mishka, i think you're chances are really high, especially for ED. just remember to showcase extra curriculars and your passions; it isn't all about scores and grades with barnard.
