Open the original- What it measures
- The page defines the score as net characters, which is total characters typed minus the number of mistakes. Because the deduction is one character per mistake at every level, a fast typist with many errors can score below a slower, accurate one.
- What it does not show
- This is the certifying association's own scoring rule, not a general standard for typing speed. Other tests deduct differently, and the rule is for this test only.
