Kotlin Core - Very usefull The teaching method in Hyperskill is great. First you select a project and you start learning topics about the project. In the topics there is two step. Technical and practical. After reading article about the topic you solve some problems about it. After finishing all topics you start writing codes about your project. This way is so usefull because you make lots of practice about topics and it makes you learn them permanently.

JetBrains IDE integration What I really like of Hyperskill is the integration with JetBrains IDE. A learning tool that integrates and gives an opportunity to get to know our IDE better (key shortcuts, preference changes, tabs etc.). When I got my PHPStorm company licence it wasn't hard to work with because I use some IDEs since 90s but still. There's a lot new options that JetBrains Academy plugin and Hyperskill help to learn. Only one thing I miss on the Hyperskill page is to have two study plans opened. Or easier way to jump from study plans like I want to learn C++ from the beginning and develop my SQL skills. Great work Hyperskill Team!

Best platform to learn Java and Kotlin The code reviews help you adopt best coding practices, the integration with IntelliJ is fantastic and I love the way the lessons are written in a concise way, much better than video in my opinion. Oh! and the exercises are great!

Learning is like a video game The fact that there are exercises and projects in every theory section. I believe you should provide the solution or some hints, cause sometimes exercises are more complicated than theory.

General impression Java basics I have chosen the learning approach without a fee in order to find out whether the form, style of educating programming topics suites me in general. I must say yes. I can recommend the form, the style. The Java basics are tought well. Also the exercises that follow chapters of theory in order to repeat the topic are designed very well as tasks of different difficulty are provided to get accomplished. Also a link in the excercises back to theory concerned is offered. A few times it appears that theory linked to support the solution doesn't stick to the task. This can be solved by reviewing the theory sections. As it doesn't take too much time I feel this is okay.
