Average hours per week put in--Harvard Extension School Courses

Hello all, I am arranging my schedule and curious. Those who have taken Harvard Extension courses, on average how many hours per week were put in per course?
I really do understand that everyone varies, but looking for an average so I don’t over extend myself with family obligations.

Thank you for any advice, tips or experiences.

If this is your first venture, take one class. That’s it. One.

If you’re serious about the class or at all interested in the degree program plan on re-watching the video in its entirety and between four and 10 hours on problem sets.
