Look at old tests and see EXACTLY what you are missing and why. If on every test, you get equilibrium problems wrong but kinematics right, study equilibrium not kinematics! Chances are, you just don't know everything yet. From my experience, someone able to answer all the flashcards and has a good verbal technique is ready to pull off a 27. Working problems and applying what you know is what will get you to 30+.
And for verbal, try a few things and see why you are getting questions wrong. I have made a huge improvement by anally looking at mistakes I make. I was able to find out that I tend to get creative on questions and try to make wrong answers fit the wrong way. I was able to see that Kaplan's mapping strategy kills me and that high lighting works for me. Verbal prep out there is so hard to apply meaningfully to the MCAT. I worked with a verbal tutor that taught me a lot. My advice though: experiment like you are a scientist by holding things constant and varying one component of a good VR method. Change timing on the passage, change timing on doing answers, Try reading and covering the passage to see if you are falling into traps, try eliminating wrong answers on the sole basis of them being stupid, extreme WITHOUT looking at the passage first. I promise you can almost always eliminate two wrong answers. You and a friend read a passage, spend 5 minutes discussing it, then answer questions.
You should be very excited when one of these approaches gets you more questions right. Now just figure out what component of this got you the right answer like different time distribution, actively thinking about the passage more than usual, going with you gut etc and learn how to apply it to 7 passages in 60 minutes.
