Any Advice/Tips on Reviewing, Especially for Physics and Math?

It's been over 2 years since I graduated university so I'm very rusty with all of the material. My test date is scheduled for 5/20 and I feel like I'm not reviewing the material fast enough - especially for Physics and Chemistry.

With my budget I was able to purchase the Kaplan and EK review books along with the AAMC study material.

Does anyone have any recommendations on how to relearn Chemistry and Physics (math)? I've tried simply reading the Kaplan books and then jumping back and forth from that to EK, but I know I don't truly understand the material.

Also, aside from the practice passages in the Kaplan and EK books does anyone recommend where else I should get questions for review?

Thanks in advance!
