Just remember rejection is a part of the process. Hard at first, then youll get use to it. But be proactive and call the schools up. Ask them where is my application, when do you guys interview, ect.
As far as your question, There are three options; We want to see you for an interview, We think your competitive and might give you an interview at a later time/hold; or the worst We cant grant you admissions at this time but reapply for next year!!
I doubt they will leave you hanging, but keep a close eye on your application status. You might be missing a stupid item like AP scores, which they decide its incomplete. So make sure your complete.
Just keep positive and i know its hard, i have been reading some inspirational books to get the stress of it off my back!!! Just get your mind off of it and enjoy the new year!!!!
