My opinion. Please find below my opinion. 1- The course organization is very good. 2- The absence of videos and the focus on reading helped me achieve better understanding. 3- The reading time for each step is acceptable. 4- The course maintains good quality. 5- The practice section is also very good.

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.

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!

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.

Very good platform to learn Kotlin. I am using Hyperskill to learn Kotlin, with both the web version and the Android application. I especially like "The problem of the day" and the option of being able to review the concepts already seen.
