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.

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.

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.

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

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.
