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.

Отличный курс! Задачи заставили реально подумать и попотеть. Благодаря курсу, я стал лучше чувствовать смысл функционального программирования и, естественно, разбираться в работе языка Kotlin :)

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).

The course was very well organized. The instructor clearly explained not only the language features but also how they work under the hood. Thanks a lot, Coursera for giving me this opportunity.

This course is a great way for learning Kotlin. Although I've been using the language for almost 2 years now, still there were some new things that I've learned/re-learned from this course.

Great work, now i can understand a lot of concepts that i didn't understand before, the course is clear and very well explain with enough examples to reafirm the concept exposed, good job

Great course. I thought it was going to be a basic course and it ended being harder, in a good way! Thanks Svetlana and Andrey for putting together this course, and of course JetBrains

I learned a lot of things!!! despite I have been using kotlin in my work. The materials and explanations are really good. One of the best courses I've taken in Coursera definitely!!!

Great assignments and quizzes to go along with videos. More in-depth than any other Kotlin course I have taken with showing best practices and reasons to prefer certain patterns.

Nice introduction to Kotlin language with all its crucial features. I'd be happy if I wasn't so busy and had more time for homeworks :-) Otherwise one week is sufficient.

Awesome course, content is well prepared & structured. Dialect is a little heavy sometimes and transcription could be better, but all together a really nice course!

Very good course. Well organized and structured. The assignments are not always trivial and some IDE problem can happen, but at the end they are useful to learn.

I would like to thank #JetBrain #Coursera and faculties whose give me opportunity to learn Kotlin, here I learn lots of new thing which are very helpful for me.

Really helpful course and good instructors. Only one problem-its deadlines. Well done! I can advice this course for people who have a medium knowledge of java!

Greatly taught by svetlana and andrey project lead. This course go thoroughly concept wise which makes this course a high quality learning material for kotlin.

I really love this course. The assignment problems are very challenging. If you want to start Android development in Kotlin, I recommend this course for you.

The course provides a very practical way to learn Kotlin. I think its coding practises and assignments are very challenging, but I have learnt a lot from it.

Very nice course with tasks which are challenging enough to properly test the understanding of Kotlin. I really enjoyed challenges in the end of every week.

Good content and nice pace. Some problems took a while to solve but it was due to change on mindset between how i java program vs how you do it in kotlin.

Great course, would be really nice incluse something about coroutines, or make a new course only with this topic. Looking forward for more great content.

Thanks for the great course. The only thing I would change, was a native speaker. I found it sometimes hard to understand what Svetlana Isakova said.

This course was phenomenal. It was perfectly well explained and helped me to transition nearly all my prior Java knowledge to Kotlin within a week.

The course content covers why we choose some functions over others, in such a clear manner, and also offers exciting programming problems to solve.

Excellent course, thanks! Clean explanations, right to the point, good for java developers looking for a modern approach. Thanks for both teachers!

Great course for people who wants to learn kotlin . The instructors were really good and exercises help you to test your learning side by side
