If I submit mine in December, do I have a better chance to get in?
Nope. They don’t look at the applications until they are all due and turned in, so turning it in early doesn’t increase your chances.
They typically spend February reviewing applications.
Andover recently sent out an email saying that their due date is the 1st of Feb, but they will start reading apps on the 26th.
I never got that e-mail…
