Yes! They’re all self-study, on-demand courses. Once you purchase a course or course package, you own it and will have access indefinitely — so you can work through the course(s) at your own pace.
The majority of courses are broken into modules and units, which helps facilitate working your way through them incrementally at a pace that works for your needs.
Our system remembers where you left off in a course if you stop partway through, so it will take you back to the module or unit you left off in! Just click the “resume” button next to the course title on your “My CE Courses” page and you can pick up for where you stopped.
