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!

Very good, but could be better! Ok, I am using the platform for a fair amount of time now, and overall I really like the format, exercises and projects. However, there are some disadvantages: 1. Firstly, the order of the topics when learning something is not natural and as it should be!!! For example, I am learning currently the Comparable interface then databases then Comparator interface (does not make much sense since both interfaces are mainly used for the same thing and should be learned after each other). 2. Sometimes, the theory behind the exercises is not discussed in the lecture. 3. And last but not the least, IT IS A REALLY EXPENSIVE PLATFORM! Actually, I believe it is the most expensive one...In my opinion it should not cost more than 20-25$ per month, but it costs 50$!!! Just unbelievable.

Its Java tracks provide a good theory… Its Java tracks provide a good theory explanation better than any other websites.

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!
