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

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.

Straightforward course with practical examples with real-world usage I got through a lot of software courses, but this one suits me the best. The theory is divided into small but logical parts and it's often connected with practice and real use-cases and that's the most valuable part of it. Some practice questions are ambiguous and needs more 'intuitive' approach. But overall, they are making the pages better and better every day.

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.

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.
