I can say that the journey is certain and what it has done for me already has been very transforming. I plan to be like the OP and be within 1 S.D. of a 40 given my last 5 AAMC's. I have studied between 5000 and 7500 hours and have yet to take a pre-req or my first AAMC.
I have been told by many that my future MCAT score is just an arbitrary obstacle between me and whatever med school that I wind up at; and, if I
believed that argument then I would not be who I am.
I'm a process-oriented person and I want a very high MCAT score, because that strive and that desire will set me on life's right path for me. I'm going on a tour of UCF's med school tomorrow and would be as happy there as any ritzy one; because, I'll be the only student I know of who truly has his priorities in order. I feel sorry for gunners who can't tell their future wife or husband that they could have went to a ritzy med school, but that love is more important than fame, wealth, or prestige (which is all the ritzy med schools offer--you create your own challenges in life; you create your own success).
I encourage everyone to pursue a 40; because, the journey alone (and not so much the result) will make you achieve more of your potential. I have learned that stuff outside my control (such as which med schools accept me) is not as important as everyone thinks it is. I'm in control of my own successes, and if I must rely on the opportunities which a high MCAT score can lead to, then I would not work as hard as I do. I guarantee myself the journey, which is why I work hard. I pursue the journey itself and the "40" is the only way I can define it; and, I encourage others to really think hard about their reasons for wanting a 40. The reason is most likely to make up for a deficit in some other part of their life. Nobody wants a 40 because they would be perfectly happy with a 36; and, those are questions I myself have answered; and, I encourage everyone who reads this thread to posit a better reason to pursue a 40 than the reason I have given...
I hope this post maybe helpful to a few open-minded gunners out there...
