I think Keith hit the nail on the head. The most important thing on verbal is to get through all the passages. Here's what I did (I got a 13-15 by the way):
I read each passage faily quickly and underlined important points.
I also tended to summarize in my head as I went along (it kept me awake). Like at the end of a paragraph, I'd think "ok, that paragraph was about blah, blah, blah". I didn't summarize in the margins like Kaplan suggests because it didn't really help me.
I tried to remember the structure of the passage - so I could find information when I needed to go back for it in the questions.
Then I would hit the questions. I crossed out all the answers I knew were wrong. I would refer back to the passage if necessary. If I couldn't decide on an answer, I circled the question and moved on. After the last question for the passage, if I had time left (9 minutes per passage only!), I would consider the circled questions again. If I didn't have time - I guessed. DO NOT get hung up on any one question, it's not worth the time. I usually had about 2 circled questions per passage.
On my practice tests, I usually had some extra time after the last passage to go back and check circled questions again. On the real test, I finished right at the buzzer.
Oh, one weird thing I did was to start with passage #9 and work backwards. On the Kaplan practice tests, this helped me because they had a tendency to put the hardest passages up front and then they got easier toward the end. On the real MCAT, the last two passages were absolutely impossible and I was feeling very frustrated by the time I got to #7. Thankfully, they got easier after that, but I'm not sure if my "reverse order system" was helpful or not.
Oh, one more thing. I bubbled in my sheet at the end of every passage.
I didn't try to "speed read". I've always been an avid reader, and I can read pretty quickly for content.
Sorry, this got really long. I hope it's helpful.
