Reenactors like us are oftentimes actually amateurs in their respective fields of knowledge. This means the majority of us hasn't gone through an academic study in history or a comparable field. Instead, we acquired the knowledge about our impressions ourselves. To create an accurate view of a historical period, many sources have to be researched with great effort. An university course, however, has the advantage that one can learn from the knowledge of a seasoned professor and thus already start with a good view of the period and a knowledge where to focus further research. This makes the courses of the famous Yale University a blessing for aspiring reenactors.
