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?

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.

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

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.

I actually want to give 5 stars, but since the english being spoken in the video is not really clear, then 4 stars. Other than that, the course is great for any programmers who have experience in java

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.

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.

Very useful course that covers all the basics (and more, sometimes!) of Kotlin.It is really well-taught, but some assignments show gradle errors that can be ignored, but are still quite annoying.

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.

4.5 Stars.Excellent course, some sections go out of their way to show how Kotlin is different from Java... maybe I wasn't so keen to learn about differences rather than just having fun with Kotlin.
