Want to finish all of UWorld but know I need to start AAMC.

I'm testing 8/16 and am wondering if I should finish all of UWorld. I'm currently about 40% of the way there and am doing about 110 questions a day but know I should start AAMC soon. Would it be too late to start end of July? Do I need to complete all of the UWorld questions? What should I do?
