With the help of the screen the user can review his learning progress and identify his weaknesses. For that a bar diagram visualizing the errors he has made during the training can be summoned:
If he has passed the lesson he may choose to start training on the next lesson right away. Otherwise he can repeat the current lesson or return to the home screen.
The score screen was the last large outstanding feature I am targeting for the initial release. With that one done only a few small ones remain I can easily finish until the Feature Freeze on October 25. So it looks like the new version of KTouch will be actually released with KDE SC 4.10 on January 23, 2013.
