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

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

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?

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.

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!!!

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.

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 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 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

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.

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.
