Relistically your wait is till May 1st, when the schools are required by AADSAS to report multiple seats reserved by the same student. It's a new policy that is being started this year. Even by May 1st you won't get a yes/no answer because the student has about 15 days more to decide which one to keep. Good luck, hang in there and just try to relax.
Your best bet is to keep calling the school which is your #1 choice and let them know how determined you are to get in.
