August 15th MCAT LATE for this cycle???

I'm planning on submitting my application late June. I know that this is not an ideal case, but my mcat is in July 20th and I think I will perform much better if I rescheduled it for August 15th. Is this too late if I apply this cycle??? I'm planning on pre-writing my secondaries after my mcat. I do have a pretty competitive gpa. Any thoughts would be highly appreciated, I'm shooting for 520+ on my MCAT
