Although they vary slightly, each course includes six to eight lessons. Each lesson consists of the following: thirty minutes of video instruction (total three to four hours of instruction for the whole course); short “office hour” videos with the professor; a quiz; additional resources from modern Catholic sources (such as FORMED), academic sources, and from the rich heritage of the Catholic tradition (such as the writing of the saints). Some courses also include a companion book, which will be free for subscribers for the cost of shipping and handling.
