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

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.

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, 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.

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!
