 We usually do it back-to-back two weeks. We'll do a session for an hour, usually at noon Eastern time, and then we'll do the next week, do the second part of it. There are some quizzes that are embedded in it, just basically reinforce the learning. We also have additional courses if people want to get a little bit more into this. I just finished a much more extensive, I think it's more of like a 20-hour course,
