All Coursera courses have scheduled deadlines called sessions to help you stay on track. All deadlines are suggested, so missing a course deadline or submitting an assignment late won't affect your grade or course progress.
If you enroll in a course but need to start at a later date or take a break, all of your progress will be saved in the meantime. You can switch to a later session and continue working on the course.
Coursera learning program schedules
Coursera learning programs set up by organizations may have their own course or assignment deadlines. You may see dates or deadlines on your learning program dashboard that are different than the dates and deadlines in the course. If you miss these deadlines, it won't affect your grade or progress in the course.
