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.

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.

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.

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.

Super useful Amazing, I've tried lots of things to learn how to code and event took some courses in university and nothing has been as useful or entertaining as Hyperskill. I wish you could use gems to unlock projects, but other than that is is great.
