Is 15 weeks with the Kaplan books, UWorld, and AAMC FL's a good enough strategy to get 505-508?

I want to take the MCAT in August. I just finished my pre reqs with a 3.2 GPA. I really don't know what strategy the high scorers are using but if I use the resources I mentioned and study around six hours a day, six days a week, do you think I will get into the 505-508 range or is there more to it than that?
