from applying in this past cycle, I have deduced that the absolute deadline to be considered for the first round of acceptances is mid August. I called a couple of schools and though they didn't directly answer my question, I have deduced that it is mid August, meaning you have EVERYTHING in. This way it will be mailed out by end of August to early September. July is perfectly fine. Of course if you have low 3.0 ish gpa, I would submit in June.
