I found an easy platform to access free online courses on a multitude of topics at courses.edx.org, an initiative by Harvard but now joined by a lot of renowned universities. (Alma mater, when is your turn?)
Currently enrolled in a course on Dante and also a course on Capitalism. Those interested in learning should at least check it out. You can actively participate in the timespan they give, or do it in an audit mode where you don't have to submit any homework/do exams etc etc for grading.
