You miss understood the majority of my post. You decided that you want to jump to dentistry AFTER you 1) took the MCAT twice 2) applied to MD and DO schools and 3) got admitted to some sort of schools (good or bad)
Now imagine that MD/DO schools are a girl/boyfriend what you basically did is to ask them out, go out for a few years, give them a ring and get engaged, walked to the altar AND THEN decided to pull the plug RIGHT BEFORE the ceremony LOL While this sounds drastic this is exactly what you did.
Now imagine I am an adcom for d-school and I read your application. Please tell me why I wouldnt think you would do the same for d-school OR tell me why I should trust that you have made up your mind rationally instead of some flaky or indecisive last minute move. "Why dentistry now?" Will be the harder question you will have to face. Again I am not saying you cannot go into d-school but mind you, you have just quit on your last gf (ie MD school) and now you want to get married all over again. Do you realize why there may be a bit of a mistrust? (also your post seems to indicate that you dont want to go to Med school but that doesnt mean you have to or badly want to go to d-school, so that makes it look more suspect that d-school is just a backup and you are not really into it.)
Also the fact that you took the MCAT twice shows you were really concerned about going to MD/DO school, it doesnt make you look better, it makes you look even worse because you were clearly dead set on MD/DO school, why else would you take the exam twice? Your points are understandable, but you must see things from an admissions point of view. All your indecisiveness should have been thought about pre-MCAT and pre-Accepted into MD/DO school. Not saying you have to control your emotions, but the point is that your gonna have to sell yourself really really hard and hope that people willing to buy your story. Im sure your stats are fine and your probably a pretty bright individual, but this isnt just about numbers, its a professional degree. People have to trust that you have finally made up your mind and that d-school is not a pure backup (as it is for 95% of all former MD students.)
Again im not here to degrade you or shoot down your posts, but I do want to provide you with an expectation for the future (should you do well on the DAT and get actual interviews.)
