Maybe I am missing something, but why are you still holding out hope? We already know 3 rounds of finalist emails went out and we know there is a history of 3 and only 3 rounds so why are you hoping for a 4th round with no evidence to support that hope?
I think if in all reality all you are is a middle or upper middle class suburbanite who isn't from and has no experience with rural and inner city populations then why would they give you a scholarship? The long term goal of the NHSC is to promote physicians who are going to stay in these areas for their entire careers, not just 2-4 years and then move back to the burbs. Besides, if you don't really want to work in these areas, you're not from there and have nothing in common culturally with the community, your service won't be as good and your pt's will know it. Quite honestly, if you have no intentions of staying in a rural or undeserved area after your commitment is over, I would hope you don't even apply. Every rural patient has had that doctor who can't hide that they are counting down the days until their contract is over and patients deserve better than that. You practice differently/better when you plan on staying in a community long term and in the medical field long term relationships are important.
