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

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.

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

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.

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!
