Some of the lectures were tough to follow. Huge disconnect between the course videos and the assignments. QuickCheck assignment was a waste of time for me. Calculator assignment is really good. No assignments related to Week4 course work is disappointing.

Pretty informative course, even if the first one or two weeks used to the part of the Intro to Scala course. The 2nd part of the lectures in the 4th week seem really disconnected from the rest of the course and are introduced with very little context.

The course is generally good, but it seems to be a bit of a hybrid of several different courses. Perhaps the videos should be updated so that references in the videos to "the next several weeks" in the last week of the course, don't confuse students.

I suspect I am not alone in finding the fourth week of this course to be somewhat lacking. I agree with the majority of the feedback regarding the shortcomings of the final week; however, as a whole this was a fun course and I learned a lot.

A good overview of functional programming concepts just like the preceding course. I wish, however, there were more material on concurrent programming. I'd like to see lectures on concurrency by Martin Odersky sometime in the future.

Assignments 3 and 4 can be improved. They are a bit hard to get started with and at the end only require a handful of lines of code to implement. It does not match the learning outcome of the difficult topics taught in the lectures.

The course is awesome... but I got myself a little lost when changing from Martin to Erick. Sometimes changing is good, by as a personal choice, I prefer the way Martin exposes the content so for me, the learning process is better.

The content is great and very practical. Most of the lectures are very clear and easy to understand. The only downside that I notices was during the week 4, where the explanation of Future and how to use it was kinda disconnected.

Very good and well-paced course. I'd give 5/5, but there are parts that seem to be missing -- lecturers refer to videos that aren't part of the course (or the previous one: Functional Programming Principles in Scala). Overall 4/5.

Great course overall. It looked though as if some of the lectures were cut and pasted from some other course into the content and were not as coherent as they could be (particularly the case with the last week's material on FRP).

A great follow up to the previous course. The planned content is great but the last week goes too fast and the last part about Future is very inadequate to understand Futures well. Also please add more content on Monads.

The course is very good overall, except for the last week (Week 4), which includes videos from a completely different course and feels really like a mash-up of unrelated topics (they are not! it's just the presentation).

Last week is awful. It is better to skip what another lecture tells on futures, this will not be used in the assignment or in further courses. And this material is better studied from other sources. Otherwise it is Ok!

The course decsribes several ideas in functional way of thinking: Streams, Monads, Reactive Programming. By the way, looks like course is compiled from several pieces that are completely disconnected from each other.

A very good course (4.5 in my eyes) the only thing for me that was lacking straight after previous course was a bigger difficulty between videos and programming excises. But maybe that's my lack of Scala experience.

The course is good, but not as splendid as the first in the specialisation. The difficulty has apparently skyrocketed, while some videos from week 4 seems to be missing, making the lectures difficult to understand.

Saw the application of some functional programming in the course. It was pretty cool, but it was a bit random. I wished we could learn more advance topics of functional programming, such as Category Theory.

Maybe an unfair comparison but I am comparing this with the principles of reactive programming. That had much more contents such as actors, etc. Having said that this is a good course by itself.

The introduction to functional reactive programming is well done. You go from the problem to the solution in a few lectures, and understand positive and negative aspects of the approach.

There were some discontinuity in the last week. The classes appear not to be from the same planning, and the teachers say about classes that are not in the course. It should be revised.

Great course. seems like some things that were referred to during some of the lectures were missing and kinda left you waiting for more. Hoping they will be completed in future courses.

There's a lot to chew on here, and it's well-articulated. Some of the examples are a bit opaque and academic - a little more of a practical, intuitive approach would go a long way.

Overall very good and somehow challenging course, however week 4 is a bit convoluted (E. Meijer referring to the nonexisting (in this edition of the course) previous video etc.)

Less material and practical tasks than in the first Scala course, also some bits about Reactive programming were just taken from other course, but not fully, just partially!

Great class, though the content seemed less coherent than the first course. Topics tended to bounce around without enough deep dives into the more abstract ideas.
