i see there's quite a lot of people who are spring admits and got that same fall messaage. i think it's just some mistake they made. but i'm still so amazed that i could actually get into this university... considering that i had horrible sat scores and so-so extracurriculars, and the fact that i was waitlisted for UCLA destroyed my hopes for berkeley. xD
man now i totally regret lying to my friends about me not applying to berkeley (i was so sure that i'd get rejected because it seems so out of my reach in my opinion...) i just really want to tell them i got accepted now. LOL
When students do FPF, they have the option of living on campus in one of the res halls. In this case, they would be enrolled for fall housing - it's not a mistake. Just go and manually change it if it doesn't apply...and don't worry about it if you're not going to do FPF.
