Verbal was the section that gave me the most trouble on my MCAT. AAMC #3 I scored a 7 VR.
On the real thing, I scored an 11 VR. Here's how I did it (copied from my 30+ MCAT post on page 9):
1. Find a quiet place to work. I cannot emphasize this enough, especially with the VR. You may be good at reading quickly in a bustling cafe, but in a quiet room with nothing but your thoughts, it's easy to get sidetracked and distracted by yourself.
2. Buy the EK 101 passages book. My entire practice centered around this one book, and it helped me immensely.
3. Do 2 passages per day under TIMED CONDITIONS. EVERY. SINGLE. DAY. I cannot emphasize it enough. Or maybe I can. EVERY. SINGLE. DAY. I started off averaging around 7 on my VR. You can see that it paid off. Limit yourself to 8 minutes a passage. If you don't know, GUESS AND MOVE ON. Review the passage either the same day or next day, and understand the explanations as to WHY you got a question wrong.
4. While reading the passages, my strategy was to read a paragraph, and once I finished reading it, I would write a word or 2 next to the paragraph about the main idea of the paragraph or something important. I never actually went back and used the words, I just thought it was helpful to keep myself on track.
So basically what I did was just trained myself for about 2 months beforehand to do passages in 8 minutes FLAT. I know it sucks to guess and move on, but it will help you get through all of the passages and eventually make it to the end with 12 minutes left for the last passage. You can use the 4 minutes to go back to a passage that gave you problems if you want to, but I never used it.
