Why does the level require a minimum speed to progress?
Actually, it does not. Speed decides neither whether you progress nor whether an exercise counts: accuracy does. To level up, you only need two things: practice volume and accuracy.
What each level really asks of you
- Accumulate the keystrokes required by the level.
- Pass the minimum accuracy at least twice.
What you see at the end of each exercise
- Goal reached!: you reached the level’s minimum accuracy. The exercise counts towards levelling up.
- So close!: you were between 90% and the minimum. Part of it adds to your practice, but it does not count as passed yet.
- Keep practising: below 90%. Slow down and look for each key.
Your speed appears alongside, compared with your average. Beating it earns you a little extra XP, and beating your personal best earns you gems. But it never holds you back.
Speed comes on its own with volume: it is a consequence of practice, not a toll. That is why the system does not punish you for going slow, it just asks you to practice more.
If you see that the level does not unlock even though you have done many exercises, look at the level progress bar: it tells you what you are missing. And if you are in a school, the teachers may have activated extra requirements, such as spreading the practice over two different days.
