Well-developed self-learning system with useful tasks. I can go at my own pace. It deepens the knowledge sufficiently. Useful forums on topics.

The most valuable piece in codegym are the practical applications and exercises. Great work with the plugin, task validation and recommendations. Very well structured lessons with examples and code entry. Overall this is the best Java learning program that i have encountered and would recommend it to anybody that wants to learn or improve his/her programming skills.

Most of all I like the form of study, like a quest with intesting tasks and pictures, with sence of humour and motivational videos. It is really good composition.
