If your app really isn't ready, then don't submit it. You don't want to look unprepared and foolish. But if you're being neurotic and nit-picky for no good reason, get over it. I submitted my application at the end of June last year, and it still took >6 weeks to get verified. I had a lot of transcripts... Oddly enough, the school I really wanted to go to, immediately sent a secondary, long before I was verified. They also had a 2 week required turnaround, which meant they had my finished secondary, before they had my verified primary. Probably one of the few schools that operate like that; but I was slightly unprepared to start receiving secondaries.
Anyway. The point is, don't unnecessarily hesitate. I'm certain that submitting as early as possible helped me get accepted. A few more weeks to sit on my submission, wouldn't have changed anything about the application I had spent years preparing. I had a below average MCAT, and probably would have been outright rejected had I waited until the end of summer. A friend of mine, with an otherwise solid app (and probably better than mine statistically), applied in mid-August, didn't get verified until October, and had zero luck this cycle.
