So I had two teachers write me a letter of recommendation, a biology teacher and a math teacher, and I requested to my guidance office that I wanted my biology teacher's LOR to be sent to ND. However, I just found out by looking at my common app form that my school sent my math teacher's LOR and school doesn't resume from winter break until January 4th, while the deadline to apply to ND is January 1. Since my school uses Naviance, I don't have control over which letters of recommendation get sent to which college, only my school does. Are colleges generally okay with LORs getting sent a few days after their deadline, as long as the application is submitted before? I'm pretty sure my biology teacher knows me better, which is why I want to get it switched. Notre Dame's website does not address this kind of issue.
