Indianjatt, with all due respect, focus on the tasks in front of you right now. I'm not sure what year you are in high school, but don't start dwelling in things so distant in the future.
Doing verbal passages this early is going to do you no good. If I were you, I would start reading for pleasure - try to read widely; magazines, books, articles, newspapers. If you can get your reading speed up, and increase your retention of what you just read, you will set yourself up for success.
Leave the MCAT studying for AT THE MOST a year before you take the test. I'm applying to medical school this summer, do you think it is wise that I start studying for the Step 1 now? Obviously not, same situation with you here.
