Re: OK, How Does Starfleet Academy Work Exactly?
My assumption is that people with advanced degrees aren't going to the academy to get a duplicate degree but to learn whats expected of a Starfleet officer and also train to serve aboard a starship and out in space. McCoy, in ST09, was operating a bridge station in the KM test. Possibly the science station since he noted the presence of the Klingons and the status of their shields. Starfleet's OCS is much more intensive and not geared to turning out 90 day wonders.
