No, all five courses are not offered during a single semester, so it is not possible to enroll in or complete all courses at the same time. Please see the articles May I take an SCx course out of order even if I have not taken its prerequisite? and May I take two SCx courses at the same time? for more information.
You can purchase all five courses and the comprehensive final at one time from the program home page here. If you choose to do so, you will receive a 10% discount for the full program.
Courses purchased as part of a program bundle must be completed within 24 months. Please visit the following pages at edX to learn more: How do I enroll? and How do I complete a course with multiple sections?
