I have applied to a few schools and unfortunately they will not all be aligned in terms of deadlines and rounds. I know this is a mistake.

My main concern is how long the time period will be to accept an admissions offer from a particular school. That is, if I hear back in early January about School A and not til late March about School B another - will I have the grace period with school A to wait for school B's decision? Additionally, School B would be a more selective school than School A.

Let me know any thoughts please.
