Theory, practice, and progress — all in one place

On the course page, choose a topic and move through it from top to bottom. Nested materials can be expanded directly in the roadmap, and completed pages can be marked as finished. Once you sign in, your progress is saved automatically.

Marking a page as completed
Completed pages are marked with a green check.

Practice without a separate “world of exercises”

After the theory, move on to practice for the same topic. You can start solving exercises right away, or get to them through the separate “Practice” section. In Ranked mode, you complete exercises, advance the topic progress, and earn rating points. The Exam is meant for a separate knowledge check: it puts together random exercises and does not affect your rating.

Seeing a mistake is a useful result. Do not rush to repeat the answer right away. First understand where your reasoning diverged from the correct solution, and only then return to the exercise.

See what is already working

Your profile contains statistics for theory and practice. They are not there just for nice-looking percentages, but to help you quickly see which topics you have already mastered confidently and where there are still gaps.
