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.

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!

I love this learning platform I love this learning platform, the only one I return to so often and so eagerly.

Very good platform to learn Kotlin. I am using Hyperskill to learn Kotlin, with both the web version and the Android application. I especially like "The problem of the day" and the option of being able to review the concepts already seen.

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!
