You have to explicitly ask if your D has a “slot” or a “tip”…with that ACT Kuster may not want to “waste” a slot on her. Also absolutely ask what percent of swimmers with your DDs level of support get in.
Make sure she has had an actual pre-read and it is positive. Do all this BEFORE you send the ED application.
The Williams swim team is a powerhouse that usually wins the NESCACs. It’s a great school.
However, you absolutely need to have a serious, no holds barred and explicit conversation with the coach.
