Cheapest District of Columbia Managing General Agent courses
Ranked on price, and only among courses that satisfy a route to this license. Exam prep is listed further down but not ranked, because it does not qualify you.
Nothing is sold for it and nothing could be. The District sets no examination and no course for this authority: what it asks for is a producer license underneath, a $100,000 bond and $1,000,000 of errors and omissions cover.
