I sent my application about a week ago and I realized that I made a mistake on my transcript. So, I ended up having to withdraw a class and retook it another semester. I had marked that class as a class that I have had to retake, but found out that I was not supposed to because withdrawn classes do not qualify for grade change and therefore I wouldn’t have to mark it as a retaken class (I hope I am making sense). Would this affect my admission? Can I contact the schools I applied to to make this change? Please help me!
