Optimal Duration speeds up exercises if you're progressing quickly, or adds practice when needed.

How does it work?
Your progress is tracked in real time during typing drills.

If your typing is accurate and fluent enough, the program suggests that you move on and lets you complete the drill in a shorter timespan.

If it looks like some more training is needed, Typing Tutor lets you complete the drill from beginning to end.

Better Results in Less Time
Thanks to Optimal Duration, your training is based entirely on your personal learning needs. As a result, you are likely to save a lot of unnecessary practice. Your overall skill level will also be better, as weaknesses are addressed immediately with extra training.
