Like other people said, take your pre-req's seriously.
If you're at a solid school, Gen Chem, Orgo, Physics and Biology will cover a lot of what is on the MCATs. So get A's, and also try to really learn and understand it. It'll make it a lot easier come MCAT time.
Also, the MCAT is changing, so take the new social and psychology courses to get in touch with those if you can.
Take Physiology, and Genetics if you can, since they'll help you with the MCATs a lot.
For the Verbal portion, you should read the news since it'll increase your knowledge about the world around you and make you a better citizen. But it won't help your score, since its not really like the verbal at all. I personally think the verbal just means that you can read incredibly nuanced and obnoxiously written stuff and have it make sense. AKA when your a doctor and you have to read a paper laden with jargo.
I think what mostly corresponds to the level of difficult of the MCAT verbal is reading medical journals. Scholar.google.com has a lot of papers, so just think of something you like and search for research about it and read whats up. I liked yoga so I read some research on yoga, and nutrition, and lots of other things. That should help you and also allow you to get exposed to what's going on in the research world.
OH but the most important thing for Verbal is doing practice questions. Do lots of practice questions. AAMC has a free MCAT practice test, do it - it'll help you a lot and your verbal too. You can also do practice questions in other books, and AAMC's own outline book - do them all!!!!!
PRACTICE QUESTIONS!!!!!!! PRAAAACTICEEEEEEEE QUESTIONSSSSSS!
