The videos are about 15 minutes on average and there are 9 modules. There is a homework sheet at the end of each module as well, which you use to capture your strategies / goals / plans for your community and reinforces the topic of the module, and then you reply to the thread in the module to give your key takeaways for each of the learning topics. Video + homework / thread discussion should take no more than 45 min. - 1 hour for each module, but it depends how in depth you want to get with the homework and what stage you are at with your community. You could probably knock all 9 modules out in a day or spread them out in chunks throughout the week, depending on your schedule. Spreading them out over a week (or two) is probably more realistic for most people and would give you more time to digest and think about the information. Good luck!
