 Users are required to solve 30 tasks that take them through the basic constructs of the programming language of their choice. The tasks are designed in such a way that the complexity increases as users progress through the tasks. Users can't move forward until the current task is completed (since the progress is determined by a unique key that is generated upon successful completion). Previously submitted tasks can be viewed as desired by the user but can't be worked on again.
