LOR’s submitted before turning in secondaries?

Hello all,

I’m applying this cycle and have about another week or so till the 2 week mark for submitting secondaries. However, I recently amassed enough scribing hours to ask a physician for a letter of recommendation. I was just wondering if LOR’s could be submitted after turning in the secondary application because as of now all my LOR’s are from professors at school. Would I just have to check each individual school’s requirements?

Thank you in advance!
