It's a pretty nice course for people who have already know some object-oriented programming languages.

You can quickly understand what is the new features compared with Java and why Kotlin was designed like this way. The thing I like most is that it showed what is compiled in the bytecode level, which helped me a lot in understanding what is going on under the hood.

Great course, great structure + exercises.

Minor thing: The English needs some improvement - it's quite hard to follow sometimes, and sometimes even the transcript fails (I read "[unintelligible]" one time).

So much new stuff... but you managed to get this into this short course, and even I took something away from it - kudos!

Sometimes it is hard to understand what she is saying and the subtitles are not very accurate. Very informative and great course for introducing any java dev to Kotlin. Thank you! P.S. the last assignment could really use some better tests and specification (the first one was quite ambiguous)

This course allows getting familiar with basic constructions and ideas included in Kotlin. The material is easy to understand and clearly presented.

I gave only 4 stars because some assignments force you to focus on a domain of exercise instead of practicing the language itself.

The course was amazing. It covered almost all the concepts.

But sometimes I felt the course was in speed. like it covered so many things in one video which I got some trouble.

The rest was good.

Thankyou Jetbrains and Coursera for such an amazing course.

Хорший и интересный курс. Но очень хотелось бы, что по по окончании каждой недели была краткая выжимка по неделе в виде pdf. Несмотря на наличии документации в интернете, а так же разных книг, было бы удобнее пользоваться кратким обзором недели.

Very nice Kotlin introduction with a good mix of videos explaining new concepts and exercises to use it in practice! Thank you very much for all the effort that was put into this friendly course. Looking forward to more courses on Kotlin!

This is a great course where you will learn a lot. Some tasks are challenging and fun to resolve. I definitely feel that Kotlin is a great language to learn and this course is really ideal if you starting Kotlin. I highly recommend

excellent explanations, the lessons are clear and well structured.

the exercises are a little too difficult, leading the student to seek any solutions even without using the best constructs of language given their difficulty

Курс замечательный, однако, как мне показалось, многие вещи достаточно быстро проходятся и не совсем в том порядке, как было бы оптимально. В любом случае, нисколько не жалею, что прослушал данный курс.

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

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.

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.

I loved this course. I believe it is really useful for busy developers who want to update/upgrade their skills to now include the essentials of Kotlin language.

This is a great course, it introduce Kotlin very well, and show me a lot about how it works under the hood, anyway, it is a fantastic introduction course.

Some of the concepts are too high level for a beginner developer to learn. And the difficultly of the task should be reduced little bit.

Please, consider recording some videos on Second try at least, its really difficult to hear woman lector sometimes and frustrating.

I believe Svetlana can speak better, this is the only problem with course. Hope you'll find some time to rerecord better audio.

It's a good course. I miss an explanation of how it could be possible to solve the last programming assignment.

Nicely explained.But I think its good for java developers only.Not that much beneficial for Android developers

Very good course. The only annoying part is that there are no solution videos for week 3 and 4 assignements.

I found the course really helpful in building understanding of Kotlin being already familiar with Java.

I had some difficult to understand instructor's english, but the content was awesome.

Muy buena metodologia, con ejercicios para practicar los temas aprendidos!
