Its the accelerated class, so each full class is 8 weeks instead of 17. So part-time is one class ever 8 weeks and full time is 2 classes.
Time wise it wasn't bad, with the caveat it depends on your background. Also each class was a bit different. For example, the finance classes were very little time as no real homework or projects, just understanding the material.
The research class is probably the biggest timesink, lots of time spend reading and writing a research paper (albeit they make it a group project).
Marketing had a good chunk of time involved as did the Ops class.
Overall, depending your background, I would plan to spend 3-4 hours a week per class plus time if the professor actually holds a class via zoom/WebEx. Some did and some just made it straight read and work.
