You have NO reason to submit these colleges on different dates. The ED school won’t be able to see any submissions to other colleges. The other colleges won’t see the ED school.
I’m still confused why you think you need to do these on separate dates. It does NOT matter. It really doesn’t.
Just complete the FAFSA and Profile adhering to the earliest deadline, and submit to every school your kid is applying to. Really, that is the most efficient way to get this all done. Just do it.
It doesn’t matter if the ED school gets the financial aid application form a month early. The won’t care…at all…as long as it meets the deadline (which it will if you are sending it a month early).
Please…please explain why you feel you need to do these submissions at different times. You don’t.
One of my kids applied to seven colleges and they all had different dates for the FAFSA and Profile. He submitted all of them at one time…all of them.
