Promotion

My husband is in the Army. Part of the requirements for promotions are college credits. We think online courses would be best, since he is rarely home, but he only needs 29 credits. All of the online colleges seem geared to a specific degree, and none of the subjects are interesting to him. Do you know of any accredited online schools where he could take random classes in interesting (easy) things like mythology, history, stuff like that? At 3 credit hours per class, we figure 10 easy classes and he’s done. He doesn’t want a degree in IT or Criminal Justice, and that’s all that seems to be offered by the major online schools. All help appreciated.
