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.

This course is a very comprehensive and detailed introduction to Kotlin. However, it would be even better if it could include the generics part which is the most difficult but quite frequently used.

This course is good to learn Kotlin basics, well structured and the exercises are not trivial. But the speaker in the videos has a terrible accent, it's quite hard to get everything she says, I had to use subtitles which is annoying especially because they partially cover the text in the slides.

I like Kotlin as a language.
I very much dislike the tests given in this course.
The tests are more about reverse engineering games and doing maths than about learning a new language.
I spend a lot of time just trying to understand the assignments.
Overall a disappointment.

Excellent coverage of core Kotlin concepts with plenty of good exercises. I look forward to the advanced Kotlin courses mentioned in the conclusion, covering DSLs, generics, coroutines, and more.

I believe that when we learn a new language, we should try to isolate the learning objectives and teach those. This course offers many complications along with attempting to explain syntax differences; and the other complicating factors are making it really tough to figure out what the learning objectives are. The content is not clear. The accent of the instructor and speech impediments make it challenging to follow and decipher. Once we do decipher the content, the exercise are obfuscating algorithm learnings with syntax. This is not a good course and I will choose another way to learn this language.

Very interesting course where you will learn a lot about Kotlin.

This course was interesting and way more approachable than functional programming in Scala course for instance. However it seems like Kotlin is still advancing very fast so there are some small issues in assigments (buildSequence is deprecated and replaced with sequence). What I noticed is that trying to implement things in a functional way was not always easy so sometimes I went with imperative approach

The course was very well organized. Instructor clearly explained not only the language features, but also how they works under the hood. This allows the student to take full advantage of Kotlin.

Clearly explained, easy to understand and nice programming tasks. I could complain something of documenting what to do in programming task, and also more smaller tasks would be useful

I liked the course. It had an interesting subject matter and excercises all in all and they were for the great majority really good. In very few instances instructions or lectures were not quite as easy to follow as I'd have hoped. One example was the even or odd test in GameOfFifteen. These were however resolved by checking the course discussion forums or just googling. Perhaps it is not so bad that students have to check outside resources and think about problems a bit. However it seems to me that having them spend a significant amount of time on understanding parity of permutations is not exactly the core focus of a programming course. Maybe a more extensive set of instructions could be given for the permutation parity check?

It's a really great way to start on Kotlin!
And by the way this is why we put it at the beginning of our own learning path (https://github.com/xpeppers/starway-to-orione/tree/master/study-path/languages/kotlin).
The only thing I didn't like were the final assignments: too much algorithmic for my taste. I'd have preferred something to prove and practice with the language and its features.
Thanks to Jetbrains!

Pros: I like nice syntax overview and explanation of why it was done this way or another.
Cons: Strong Russian accent makes it hard to listen to. Video is for beginners but Practical tasks are for Intermediate developers. I would simplify last practical task.

I was a bit disappointed, that i didn't get feedback from a human instructor (for the assignments)
For my taste there was a bit too much math knowledge necessary to complete the game of fifteen assignment.
The explanations in the videos were good.

El curso es muy completo y aprendes muchas carácterísticas sobre Kotlin adaptadas a programadores de Java. Por otra parte los ejercicios son complejos y requieren de mucho conocimiento de algoritmia.

Nice course. I liked the level. I really missed discussions on the assignments. It would have been really nice to see a solution with comments and compare it with my own to learn from my mistakes.

Great course but I won't give 5 stars because exams lack some explanation. Fortunately, some of us already asked the questions on the forum :)

Concise introduction to Kotlin. Challenging exercises. Some digging may be required to understand what is needed to accomplish a task.

A course worth doing due to their assignments. Opens up the mind. However they need to make their problem statments more simpler as doing this doesnt offer a job in Google. :) Feedback would be to work on the discussion area and be more active for the people who made this course. And work on the content. Overall I am happy I went through this course.

Although a good introduction course, but the assignments were not relevant to the course material. They were mainly collections focused than anything else. Would have been real helpful if there were more hints around how to solve a assignments, in a more Kotlin idiomatic way.

The assignments could have been a wee bit simpler, though they do test aspects of your knowledge of Kotlin, it felt like it was more of a test of your knowledge of algorithms with a lesser focus on using the concepts you just learned.

Starts really good, but with week 4, it seems like Jetbrains lost interest in the course. Week 1-3 will show you the “kotlinish” way after the assignments, but after that, the only feedback you get is if the unit test passed or not.

I overall enjoyed the course and found it very helpful for a Java developer starting with Kotlin. I'm looking forward to more courses from JetBrains, especially one on coroutines.
At first it bothered me a little that Svetlana was speaking freely (i.e. not reading a script), because she often interrupts mid-sentence and starts over. But in the end I'm thankful that she did it that way, because it's a refreshing difference to the often sterile presentations found with other courses. You can almost "hear" her thinking. There's this one moment somewhere in week 5, where you can hear her frustration over not being able to transform her thought into speech at first try. It feels authentic.
For me, the time estimates given for the assignments in Week 4 and especially 5 was too low. It took me more time. The assignments were not too difficult, but the pursuit of finding an idiomatic solution took more time.

It was a wonderful experience to learn Kotlin from Kotlin designers. I am now a big fan of Andrey Breslav and Svetlana Isakova. Thank you guys! Completing this course was not an easy job for me although I have prior experience in Java. The assignments were comprehensive and required a lot of effort in terms of algorithms and Kotlin syntax. I am feeling happy that I have learnt core concepts of Kotlin as well as functional programming. Besides the syllabus of this course, I also watch Andrey on Youtube to get to know about the latest addition in Kotlin "the coroutines". I'll also try to convince my colleagues and management to give Kotlin a try. Let's see!

It was fun to play with Kotlin for the first time. The course is short but seems to cover everything I need to start writing code in Kotlin. The material is well-structured and the exercises quite entertaining. Svetlana is active on the forum and helps to solve all technical difficulties one might face. Highly recommend everyone who wants to take their first steps in Kotlin. Thank you very much for the course! I enjoyed it a lot. PS I'd love to see more courses like that from JetBrains i.e. covering coroutines and Kotlin Native.

I think the course videos explain everything very well! The tasks are fortunately not too simple, so you are forced to code (what's good). I recommend this course for all developers with programming experience who want to get to know a really nice programming language.
One comment to this Guy who has only awarded one star due to linguistic deficiencies: How does it matter? I come from Germany and of course I have a German accent, so what? I understood everything Svetlana explained, I guess you did too!

I think this course is very useful for someone who used java lang but wants to start using Kotlin to programming & to develop!
I'm an android developer, from Taiwan, completing the course and love it.
My English is not very well so I cannot speak how thankful for this course.
Thank you, Svetlana and Andrey.
Here are my words in Traditional Chinese:
很感謝這堂課藉由深入淺出地講解、問答與撰寫程式作業，給予我許多基本觀念。其中 byteCode 層面及 Kotlin syntax 於 Java 中的實際意義給了很多幫助。特別喜歡 Andrey 於採訪影片的談話，非常有意義！也感謝 Svetlana 努力地解說，謝謝你們！非常期待之後的課程拜託快點出吧！！！
