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.

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.

The best place to practice skills The best place to practice skills that I have found. They are not trying to be hip and clever, just straight up skill development. There is enough repetition and enough exercises to produce actual learning. One drawback is the semi-gamifying of the platform. Sometimes getting it wrong is instructive, but if you run out of lives, too bad, wait until tomorrow. Even DuoLingo does better than that.

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.

A great website for beginners A great website for beginners to learn both backend and frontend programming. Of course, some topics may not always be thoroughly explained, but overall, it's an excellent place not only to study development but also to improve your English language skills. Solid five stars. The only drawback is the high cost.
