Pros
Pro Courses offered in a variety of languages (with transcriptions available)
Coursera offers courses from all around the world, resulting in courses taught in English, French, Spanish, Chinese, Russian, Turkish and a long list of others. Transcriptions for a large number of languages are offered for each course.
Cons
Con Courses are not always available
Courses are run on set dates, though some courses provide access to the material whether or not the course is running (however, there will be far less student activity in the forums when the course is not running).
Some courses only make their material available when the course is running, so you may have to wait a long period (sometimes months) for your course to be offered.
Con You cannot take the full courses for free
While you used to be able to take courses for free and earn a statement of accomplishment, this is no longer the case. You can only audit the courses if you are not paying. Coursera makes it seem like you should also do the quizzes, but the submit button says "Upgrade to submit".
