Hi, ok, I may not know this but I've seen quite a number of universities encouraging early submission. I also believe that universities with rolling admissions review applications as they are received, so in this case first come, first served. For example if 2 people had the same profile and there's a place for one, and maybe one applied on the first week and the other on the last week, I believe the one who applied first would be given the chance. Just my thoughts. Lol!
Good luck!
