I read on this page (https://appsupport.commonapp.org/link/portal/33011/33013/Article/90/Can-I-submit-my-application-before-my-recommenders-submit-their-forms) that I could submit my Common App before my recommenders did, so long as they uploaded their recommendations before the application deadline. I did this with several schools, but they’ve already downloaded my application (well before the January 1 deadline) — will my teachers still be able to submit their recommendations?
Yes, they can. Teacher recs can come after the deadline, if the teacher does not get it in on time. Most schools will not penalize you for something out of your control.
