So my AADSAS is all complete and ready to be sent to the schools except for one of my letter of recommendations. The professor is out of the country and has told me that he will be able to send it when he gets back in about a month. Is it a problem to go ahead and submit the application as is and AADSAS will then forward the letter to schools when they receive it or do I need to wait for a complete application before sending it off? Thanks!
