How to boost b/b and p/s MCAT score

Hi everyone, my mcat is in about a month and on a practice test 2 weeks ago i got a 510. I want to get at least a 515. I think my biggest problem is not knowing enough content in psyc soc and biology. What would be a quick way for me to learn the content for those sections? I am also in school so I can only study around 4 hours a day. Also does anyone have any good cars strategies?
