For example, I said I took December 2018 and October 2019 SAT on Common App but I actually send December 2018, March 2019 and October 2019 scores to the college. The other informations ar correct. Will that affect my application?
They might be a bit confused, but you definitely aren’t the first to do this. Depending on the school, they’ll just look at the score sends and some might just look at self-reported.
