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.

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!

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.

I so far found it a great platform I recently came across the platform by way of a web search on a technical subject; I decided to read on and explore the site. I'm currently a non-paying member enrolled in the data science study plan. I find the project- (portfolio-) based training constructive as well as the grouping of topics towards a given domain, e.g. data science. I already have a background in Engineering and found the topic coverage suitable and looking forward to complete a project; I will likely become a paying member.
