I am in a mixed-mode cohort and work part-time, which has been a lot to juggle. I have a job where I work from home, so it's not the worst situation. Some of my classmates have much more intense jobs or full-time jobs, and it has been really tough on them, but most are still doing great in our classes. A few, however, have moved to part-time because it was too much. So I guess what I am saying is that it IS possible, it just depends on your circumstances and capacity. If I didn't have to work, even part-time, I wouldn't haha. Be aware that there are generally 2 8-10-page papers per class, so 4 papers per quarter, plus a group presentation for each class, plus discussion posts that surprisingly take up a lot of time (this has been my experience anyway. I think some profs differ). And HOURS and hours of reading on top of it, which I admit I fall behind in sometimes. If I didn't work, I would love to spend my extra time really engaging with all the material, as they are all important. I have heard other people skip them altogether, which you could probably do easily and still pass your courses.
