You could turn this into a poll if you actually want votes. If money isn't a factor, go with whatever will give you the best odds--ie, if a post-bac program has a linkage or a particularly high success rate, do that. If money is a factor, go with what is cheapest (take into account the cost of living in a new place...St. Louis is relatively cheap). There isn't any reason to leave Vandy if you're not going to give yourself a leg up with the application process or save a few bucks.
