I just got rejected from my top two Macaulay Honors choices (City College and Hunter). My third choice is Brooklyn College. Is it still possible for me to get accepted into Macaulay Honors Brooklyn College? Or is there no hope? Would talking to my college counselor and having her call the office help me at all? I’m very disappointed right now 
Yes, it is still possible for you to get in…but most students usually get into their first or second choice.
If you don’t get any reply from Brooklyn College, I would consider calling them or contact them somehow.
