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.

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!

Improvements It's a good learning platform, however there is a bunch of ambiguous questions with unclear answers or questions with wrong andwers in React js where there is said to remove the App.js file.

No daily life replenishment The app started out great, it was quirky, fun, and intuitive. I was planning on using this daily. About the 2nd or 3rd day I got a few questions wrong, and eventually spent my daily lives limit. Came back the next day enthusiastic and the lives never replenished! I figured it was a glitch. 3rd day, same result, no more lives. I waited a week and still nothing. So I uninstalled the app

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.
