I recommend that you read news, politics, economics, humanities, sociology, boring subject articles, and summarize each paragraph and then write up the main idea (one sentence summary of whole article) for each article. Do at least 5 per day, and try to have someone who is good at reading - an English major or very literate person - read the article and give you advice on your summaries and main points. Most universities have English/humanity department tutoring that's free so if yours or one nearby has free tutoring, you should utilize that resource. I realize this may seem to be really inconvenient and tedious, but it is well worth it. I have been studying for verbal using examcrackers, and princeton review practice passages, and most of the answer choices can be eliminated based on inconsistency with the main idea. If you have have more than 4 months, this would be very useful since your reading comprehension can significantly improve in that length of time.
If you have less than 4 months don't waste your time doing what I mentioned above. Focus completely on doing timed passages/problems, and analyze all questions and understand why each of the wrong answer choices are wrong. Make sure your reasons for their fallacies are accurate, and do at least 2 passages a day (but try to do much much more than that). Don't do many passages all in a sitting early on; try to do 2-4 then switch to a subject that is easier for u and then do 2-4 more and then switch.
Also, if you're planning on working on verbal passages, do passages for a subject that you're more comfortable with first and then move on to verbal right after. This helps because I have found that when I jump straight into verbal, I end up being unable to focus and attack the passage. When I do Gchem/Ochem (my comfort zone) first, it prepares me mentally to do verbal.
Diet is a big deal. I try to eat some sort of fruit, usually banana, before doing verbal since the brain uses glucose and basic sugars for metabolism. You want to supply your brain with the nutrients it needs before doing one of the more mentally taxing sections of the mcat. Not making good diet choices in studying for mcats is as bad as not eating a high-protein diet and working out.
Get examkrackers verbal book, and read through all of their text/nonquestion portions first highlighting their most important pieces of advice to you. Then go through again and work through their exercises and their questions. I also recommend their 101 passages book; it works well with their verbal book.
Other than that, good luck, study hard.
