I was accepted into a school ED2 last week and planned to withdraw my RD applications today. Today I received emails from 3 of my RD colleges confirming that I withdrew my applications. I was quite confused because I had not withdrawn them yet. I called the admissions office of my RD schools asking about this and they said that Common App automatically withdraws ED applications upon acceptance. Has this happened to anyone else?
I applied ED I and was accepted but forgot to withdraw one of my open applications and still received an acceptance. Maybe since your guidance counselor also has to sigh the ED agreement he followed the instructions and withdrew the applications. Hard to say for sure.
