Excellent course, packed with relevant content and useful hands on Kotlin exercises with great feedback based on Coursera provided unit tests. Looking forward to more Coursera courses from JetBrains.

Thanks JetBrains team, the course is as great as all the things that you do!
Now I am going to visit Kotlin island (Kronstadt) to see lighthouse on your logo (I leave nearby in Saint-Petersburg).

For people coming from a pure Java background, this course does a good job of covering quite a lot of topics playing to Kotlin's strengths and motivation for use.
One can see the instructors have quite a firm grasp on the overall knowledge domain (as expected given they are part of the team of language creators).
The text and speech of it does look like it requires a bit of a review, with the subtitles (I believe auto generated) got themselves in quite a bit of a tight spot, with multiple misses in words used which was case for quite a lot of replaying certain bits of video while trying to understand what was said.
Exercises wise, there was a hard balance struck there. Some of the exercises presented during the ongoing video presentation did a good job in exposing some of the functionalities that were being presented. Coming to programming assignments, however, this is a bit lost, with the emphasis being more on implementing the requested functionality with not much guidance provided on whether the correct language constructs are being applied, mainly towards the final two weeks of course. When a person has no firm grasp on these functionalities, it does serve to demotivate a bit.

While the content of the course goes into a lot of detail I found it a bit disappointing in terms of the questions asked in the lessons and the assignments. When covering the material, the questions asked most of the time aim very edge cases and don't add up to what's been learned. Sometimes it's difficult to follow the lesson, being a mixture of new concepts and the difficulty to understand the teacher. The last assignments are very hard, not because of the language itself but because we have to work out difficult algorithms that are not what we are learning. I think the questions and assignments should go hand in hand, and this fact makes it very hard to continue with the course and pass the assignments.

The content of the course is very good. It covers lots of interesting things. The fact that there is a comparison between Java and Kotlin is a plus. Mind you all, this course is not specific for Android developers - it covers a wider range of topics. That said, you can certainly benefit from it.
Why the 3 stars? I found it very difficult to engage and follow the course because of the instructor's accent. I had the auto generated subs on, but there are way too many mistakes in them. So, as an overall experience, it was really frustrating and it took me way more time and concentration as I had to stop the video again and again in order to understand what the instructor said.

Content is pretty good, but the English of the teacher could really be better. English not being my first language either, I understand how difficult making a course in English is. However, her accent is so strong that it makes the whole learning process much more difficult. I had to basically mute the author all the time and use subtitles to have a chance to follow.
Please use a native speaker to create those courses next time. The English of the lead of the language is perfect for example.
Other than that, the content of the course is pretty good, and I did learn stuff. So thanks a lot.

The course is quite good, but there is still something to improve, e.g.: lecturer's speech (sometimes really hard to understand), english subtitles in videos (there are major mistakes, that could confuse the listener - e.g. "enlightened" instead of "inlined", ...), no solutions for programming assignments in week5, and for last task in week4 (I'd like to know, if my solutions are principally good, or not - but unfortunately I'm missing feedback here).
Nevertheless, I can say, that after completing the course I know much more about Kotlin, than before.

The explanation is very good. After your work passes the unit tests, you get a useful and detailed official solution of the author. But only for 3 out of 5 weeks. For week 4 and 5 you don't get any feedback at all. And these are assignments on which Jetbrains estimates you to spend 5 hours on. I mentioned this 2 years ago on the forums, but no response from JetBrains. Otherwise I would've rated this course 5 stars. Btw I don't mind the Russian accent at all, it's very well presented. And I'm not an English nor Russian native.

The course material was great and the instructor very knowledgeable. My main pain point is the instructor's very thick accent. In my opinion, this course should be taught by someone who has a more "international" English. Having to decipher what the instructor is saying adds cognitive overhead to a subject-matter which already requires a lot of cognition.

Overall it was good, and also the information and assignments was Ok, but the accent of the speaker was annoying. Maybe it was not the accent, but the feel that the video is not properly prepared, cut, post processed without slips of the tongue and of course a lot of "under the hood" :D

Explanations were great (if not a bit brief), but assignments were really extra complicated and at times, vaguely explained. Sometimes, it would take hours to understand things, only to have a different explanation in the forum and accomplish it in minutes.

This course definitely will give you overview of Kotlin lang features (which are commonly looks like syntactic sugar, but unfortunately program assignments are to complicated.
Alson the course a lit bit outdated (no videos on coroutines, type aliases)

The course content is very great. The teacher (Svetlana) is also very good as well. But I sometimes find it difficult to follow her sentences. I think it'd get better in time as she becomes more fluent in English.

Binged it on a weekend, that was a bit much, it's a lot of work, most of it is barely Kotlin related. Still, good content, and definitely helpful to immerse.

The presenter of the course needs to GREATLY improve her English (pronunciation, word/phrase order, intonation, etc.).
