The assignments don't have a detailed explanation. There should be more of code provided with fill the blanks kind of tasks. This would make it much easier and helpful as the assignments are tough.

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).

G​reat introduction to the basics of Kotlin for experienced Java programmers. Highlighted a number of features that make Kotlin a compelling alternative to straight-up Java.

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

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.

The course is nice and quite informative, but it is almost impossible to understand what the presenter is saying. The only way to get through the course was to mute videos and go for subtitles.

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.

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.

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.

Good survey of Kotlin language features. Would have been nice if assignments focused more on Kotlin idioms. Perhaps that's a fundamental issue with using an automated grader?

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.
