Hey a fellow philadelphian!
I've used a couple books and have been experimenting with some different techniques that are out there, and I have to agree with the above poster. Examkrackers seem to have the best grasp on the mcat material and the questions that are asked on it. They have a couple of techniques which I found interesting and thought could increase my score with sufficient practice. So I would recommend looking at their books.
I also heard the Columbia review has a pretty good verbal section.
