Ok, I skimmed this a bit, but from what I get you are thinking of applying without finishing the undergrad degree. I wouldn't do that. Yes, people get in that way, but they are pretty rare. I think most the schools I've interviewed at have said some number like 0 or 1 per class. While I don't doubt you're sincere maturity and desire to be a doctor, the odds are stacked against you. It is worth it to finish the degree no matter the time or cost, you will be sorry if you do not have it I believe. You may change your mind later about medicine and be very sorry you do not have an undergrad degree completed. I know you probably feel that won't happen, I feel that way too, but sometimes you never know. Also, realize you are up against applicants who frequently not only have a BA or BS, but already have PhD's, MA's, etc. It is terribly intimidating to sit in admissions offices/interviews with such highly educated people.
Also, if we are talking BS or BA, my advice would be that it simply does not matter. I say this because my AMCAS actually has a mistake on it; it says I'm getting a BS when it's only a BA. I've corrected this at every school I've interviewed at, and all the interviewers have waved me off literally saying "ok, whatever, degree something, just write it somewhere for the logisitcs, etc." And I've gotten into all the schools, so I don't think it matters. Not to down people who work harder for the BS, but that's the response I've gotten.
Good luck.
