In case you want to decide how long the drills should be rather than letting TypingMaster guide you, you can always turn off the Optimized Duration.

To turn off Optimized Duration:
1. Click OK to return to the lesson screen
2. Click 'Adjust course duration' button
3. Click 'Turn off Optimized Duration'

With Optimized Duration you will get the best possible training to meet your personal needs as well as save time!
