@lavishdolphin Brown is a reach for everyone. If your swimming was in their range it would help perhaps.
But if you don’t mind doing the application work, nothing wrong with a reach or two as long as you have a good safety, which you do.
EA (early acceptance) is “generally” a school accepts you early, but does not require you attend (although most require you only apply to one “EA” or “ED” - although some allow you to also apply to EA state schools.
ED (early decision) is “generally” a school accepts you early, and you commit to go. You usually can only apply to one ED (although some allow you to apply to a state school as well.) If you are accepted you are supposed to pull all other applications. The one way out, usually, is if the financial aid package is unworkable.
That is great on the swimming front. If you are good enough to get interest at those schools, there are probably some other DIII’s that might like to have you.
