Hi Boloshagai, thank you for your question! There are two course types: evergreen vs cohort. Cohort Courses typically have a set start and end date for the group, which means you can expect to get replies from the fellow learners and creator. With that said, you'd always have access to the course material even after the cohort ends. For 'evergreen' type courses, you can join and consume courses anytime. Hope this help!
