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.)

This course was really great. It help to broaden my knowledge.

Very interesting course. Four stars instead of five because it was less about "Program Design" (from the title) than I would have liked.

Very good course but not as good as the first one :

Try monads are never introduced but are referenced by one of the lecturer.

Signal DP for mutable state encapsulation is introduced, but it's benefits are unclear until the research paper is read.

Exercises are still very carefully designed. Thanks for the great contents !

The course was nice but not structured very good, especially week 4. From time to time you have a feeling that this course is more like a compilation of lectures made for other courses with similar topic. Especially confusing are moments when during the lecture author references previous materials you expected to know from lectures you've never heard. That's strange.

Actors were missing.

Less interesting than the other Scala courses but still great!

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.

This course has been very good, and i will recommend it to anyone who wants to learn functional programming.

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.

Thought provoking exercises.

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 last few 4th week's videos seem a little bit messy, some lessons referenced are definitely missing and Futures part is quite confusing and not very useful (I mean, "guys, just go and read about it online" would bring more value per second than watching the videos).

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).

Very good course. Sad that it is at the same time as the Functional Programming Principles in Scala, which is clearly a pre-requisite.

Sometimes the exercises don't match the content exposed for that week, but in general the course is really interesting

Excellent course, but some topics missing from original course

Wonderful course, except for the hipster slides in the last week

Nice course to learn how Scala is different from Java.

Offers outstanding depth in parallel concepts and the weekly programming samples are really interesting and fun. Some good community discussion but not a lot of participation by instructors. The theoretical material is covered very quickly and there are not a lot of practice exercises to master those concepts.

Thanks for this course!

Only one times i was very confused - when i saw that in the last assignment i should use Vars and Signals, not Features and Promises - that's, i think, a little bit far from as async code in real projects, which contain promises, features, actors etc.

But anyway, thanks for all of that, it was useful for me.

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.

A bit lost sometimes. The course was remodeled after previous ones obviously and it seems a little chaotic sometimes. Not sure to get all the message that was intended to be passed. Sometimes the exercice are way simpler than the session contents. Still I've enjoyed (almost) every moment of the course and I am eager to go on! Thanks!

很好 ，但是因为又删减，所以感觉不是那么连贯。所以四星吧。比如最后一章，其实内容很深远，但是作业却没有考察到课程所说的内容。

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.
