It took me much longer than expected to finish the course and sometimes it made me feel stupid and helpless. Diving into functional programming was a mind bending experience, totally worth time spent!
As expected Martin is awesome in explaining principle of functional programming. I have started reading the book as well to make sure I keep up with the knowledge which I have gained from this course.

This was a decent overview of FP principals, but a poor introduction to the Scala language. In fact, the requirements should just come out and state that you must have prior Scala knowledge to most thoroughly appreciate the course. The last 2 assignments may have been ok for 3 hours (doubtful) for someone with Scala experience, but they really should be marked more appropriately for time for those of us new to Scala. I'd say 6 hours; easily more than that for the last assignment.
Also, no slides or related handouts are provided. If you remember seeing something on one of the slides shown, you'll have to look back, scanning through all the videos trying to find it. This is a very poor way to manage course content - forcing students to rely solely on the videos.
I'm left feeling I've only learned a smattering here and there of Scala, and don't think I'll take the remainder of the specialization as I had intended.

This is a reasonably thorough introduction to the principals of functional programming in scala, but to fully grasp the material presented I found it necessary to include supplemental material such as the functional programming in scala book by Paul Chiusano (forward by the course instructor funnily enough). One point of frustration however was the near total unavailability of the course TA's or instructor. Also because the only forum for interacting with them is entirely public it's impossible to receive any formal code review apart from the automated tests they run when you submit. There were multiple occasions where I wanted feedback on not just the technical correctness of my solution but also to know if there might have been a more idiomatic or generally efficient (read: tail-recursive) way to express some peculiar bit of logic.

The first couple of weeks were awesome - love Scala the language and the whole functional approach, and the detailed description of how the language actually fits together.
Also love how the homework teaches you how to setup IDE, create unit tests, and submit actual code as homework - not just workbooks and multiple-choice quizzes like in some other courses.
But why oh why was it necessary to go in specific detail over how to define natural numbers from first principles using classes, or spend a whole week on lists, etc? All that might be fine for general education in a university context, but as someone who does want to understand Scala, but from a perspective of getting cool things done - that bit was a total waste of time.
Would be a better and shorter course if those 'didactic' bits were trimmed.

I completed this course in a single day (about 8 hours) having substantial experience as java programmer. However I feel that if course is to teach Scala, it should not be so heavy on all functional programming tricks (which in the given examples and assignments are often too artificial, inefficient and awkward). Or if the course is to teach functional programming, probably Scala is not the most user-friendly choice. Also as a developer I feel displeased with assignments stub code poorly formatted with indentation bORken both in classes and functions.

Mixed feelings.... The course seems to have been a bit botched upon several updates as the material is almost 10 years old. Assignments and video lectures feel out of order and the assignments demand that you spend more time trying to understand the arbitrary problem presented rather than teaching you Scala or function programming. I don't feel that I've benefited greatly from going through this course because the material was too focused on staying theoretical while explaining a concept, nor do I feel I have any great understanding of Scala now.

Important questions are left unanswered (for years!), instructions of certain assignments are incomplete and leave the student to guess (esp. when questions go unanswered when asked). Love Odersky, but this course as organized and presented is a real let down.
Update: Great potential to learn very useful concepts if you can push through in spite of the issues. I am going to press on with the follow-up courses in this specialization. Genuinely hope this course is updated and fixed so that others can complete it without unnecessary friction.

The grading seems to round up to 100%, which makes the assignments that are already generally easy far too easy. I took this course instead of just doing my own thing so that I could get some structure and motivation. While there was some structure, it was quite basic, and the motivation was diminished by "good enough" not being much. I was considering taking the later courses in the specialization, but I'm afraid that without real grading I won't learn as much as if I learn more slowly outside of Coursera.
Great content but the rhythm is a bit fast, I didn't feel fully equipped to manage exams, indeed, each of them took me at least 2 days to solve and I have rage quit for a complete week for the last exam. I'm going to redo some of them before start the second course.
Apart from that, the format is cool and it's pleasant to watch the teacher solving the rare mistakes he did with ease.
