Nov 12th 2025I'm excited to introduce a completely new exercises engine! I've rebuilt all exercises from scratch so that they feel like a modern web app instead of a static website. Watch the video below for short presentation.
Key Features
Progress Tracking: The engine now tracks your progress as you work through exercises, so you don't have to remember which exercises you have already completed.
Exercise Categories with Progress Indicators
Exercises List with Progress Indicators
Progress Summary After Exercise Completion
Clean, Distraction-Free Layout: The new design focuses entirely on the exercise content. You can enter fullscreen mode to answer exercises without distractions.
Answering an Exercise in Fullscreen Mode
Instant Feedback: Get immediate feedback on your answers. You don't have to answer all questions to see the result.
View After Correct Answer
View After Wrong Answer
Keyboard Shortcuts: Navigate through exercises without touching your mouse - perfect for faster practice sessions. You can change settings to see keyboard shortcuts.

I hope you enjoy the new exercises engine! If you have any feedback, please let me know. Enjoy learning Polish!
