There is room for explanation on college applications; however, on medical school/graduate school applications, there is no designation or space to explain the circumstances of taking a course, except if it is tied into the "why I want to persue this career" short essay (which might be the case if the license directly applies to that career). They tend to be more of a "hard numbers" application, unfortunately.
Transcripts from every college attended is also a requirement, which can be a huge pain if a long period of time has passed since taking the community college courses (not on current file...). I would imagine that not being granted credit when an undergrad would solve some of the problems, but the application service, as well as the school at which one matriculates for medical school, will still require the transcripts. In addition, many of the pre-med advisors/guidance counselors had no clue as to what was required for the grad/med school applicaitons with respect to courses taking before matriculating into college full-time or graduate courses taken as an undergrad. If he ends up in a situation requiring previous transcripts, find out EARLY, as it was very difficult for me to get the proper transcripts...
