Would recomend if you're someone familiar with Java and looking to get into Kotlin.

I'd say it takes less than the 5 allocated weeks if you practice at least twice a week.

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.

A great course that covers perfectly the kotlin base for java developers. I was pretty excited through the whole course because it was very interesting and well teached.

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!

The only good course I could find where you can learn Kotlin if you already have strong programming bases and don't want to re-learn how classes and variables work

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.

T​op-notch course, lessons were sweetly concise but informative, assignment weren't impossibile but nonetheless demanded some effort, I really loved it.

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!

5 stars becouse it was my first course and I loved Kotlin

// Для русскоговорящих - перевод ужасный! Знание английского - обязательно на этом курсе!

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

Essential course to start developing using Kotlin. Even if you already have experience, it helps consolidate concepts and avoid bad practices.

I would like to have some hint for project tasks. Is annoying to not seeing your solution until I uploaded my working solution for all tests.

Very good course. I hope they will follow up with more advanced courses AND in the meantime, give ideas/links/references for further study!

Awesome course which explains the basics but diving into the purpose of each feature added and gives a clear view of how the language works
