Do you understand that your sons financial aid award at a Profile school is going to be based on the data from the Profile…not the results of the net price calculator?
I will say it again…I can’t think of a reason why your son wouldn’t just submit all his schools at once…
But you don’t seem to want to hear that piece of advice. So do what you want to do. Submit all the EA schools by their earlier deadline. Then go back into the Profile and send to the ED school whenever you feel like it.
