Pros and cons.

Sometimes it's hard to find in this course needed information to solve Assignments.

But you have to dig deeper from outside sources.

I subscribe to Coursera so I can take as many courses as I like for a monthly fee. There are a lot of excellent courses on Coursera but this isn't one of them. I would be really angry if I had paid specifically for this course. There are issues with the practice quizzes that were pointed out in the discussion forum months ago for which there is still no reply. Staff should at least glance at the forum to see if there are any problems with the course material. The lectures cover the simple ideas, but the harder material is outsourced mostly to http://mathonline.wikidot.com/ and sundry pdf documents. Some of the reading material is a lot more advanced than the course itself.
