Am I cooked?

I plan on taking the MCAT in late January, but I've been procrastinating so much this summer in regard to my studying. I bought the Kaplan books but haven't even completed one yet. I've also been hella lackadaisical with the anki review. If I really lock in now, do you think it's possible to get a 515+? Is 4 months realistically enough to study for the MCAT and get a good score?
