My daughter applied ED to her choice school. She was a recruited athlete and we were told she would be admitted and they would meet 100%need. However, she also applied RD to several other schools through the Common App. She received acceptances to three schools in December including her ED school. What I found interesting was that after we sent in the deposit to her ED school I checked the applicant portals for both Vanderbilt and Swarthmore and it said she had withdrew her application. We never officially notified them or withdrew but somehow they were aware she had committed to her ED school. I figured it was a feature or the Common App or the schools have an eternal system. It is interesting .
