Title^ Couldn't get a straight answer from AACOMAS. But I am planning on submitting (to only one school as a 'throwaway') soon, but I am waiting to meet with someone to ask them for a LOR. Can I submit then add a letter request later then submit the rest of my apps?
Once you add your LORs to AACOMAS, schools will receive/update these letters to your application once secondary applications begin to be sent out. You should be able to add letters all throughout the cycle, or at least until you reached the max amount on your AACOMAS application.
