Has anyone here participated in any of the free online courses offered by institutions like MIT, Stanford, or Coursera? 

I hold an undergraduate degree in Environmental Engineering and have spent my career in Software Engineering and general management. 

In the upcoming year, I will have more free time and am thinking about enrolling in one of these courses. I’d love to hear about others' experiences. Over the years, I’ve engaged in continuous learning through reading blogs, books, listening to talks, and attending some formal professional training. Now, I find myself craving a classroom environment and a more structured curriculum. 

My main dilemma is whether to pursue a course in computer science—so I can compare it with what I’ve learned on the job—or in the humanities—since I didn’t get that exposure during my college years.
