The tutorials and workshops were designed and tested as half-day workshops before being produced as a full-length self-paced course. The course is designed to be completed in 13 weeks, but you can go at your own pace. We estimate that it will take about 2-4 hours per week to complete the course content.


Learning as a team, club, or party is highly recommended. We've seen great results with teams of 2-4 people. We suggest that learning teams watch and work through the course before meeting once a week to discuss what they've learned in the shared context of the team. We've found that this approach is more effective than watching the course together as a group!
