Courses are offered all year except on some holiday weekends. We are also closed for two weeks around Christmas and New Year. All courses cover the exact same material regardless of the format followed.
All courses take the same amount of time.
The only difference in the formats is the days of the week on which they take place. Each course has Classroom 1 followed by Range 1, then Classroom 2 followed by Range 2. There are benefits to both. The San Francisco multi-week format takes longer in elapsed time, but it does not consume your entire weekend. Well, one reason is to give you a choice, but it is really because of the availability of the teaching facilities.
