Find the keys you actually miss
Most people's mistakes cluster on a handful of keys, often punctuation, capitals, and the letters reached by the weaker fingers. Practicing everything equally spends time on keys you already know.
Vocabaura tracks which characters you miss most during practice and suggests drills that target them.
Slow down by a notch, not by half
The pace that produces clean text is usually only slightly slower than the pace that produces errors. Drop back just far enough to finish a line without corrections, then rebuild.
Do not fix mid-word
Rushing to correct an error the instant it appears breaks your rhythm twice. In practice, finish the word, then correct, and note which key caused it.
Errors also cluster where your hands leave home position: the number row, the shift keys and the punctuation on the right-hand edge. Returning your fingers to the home row after every reach removes a surprising share of mistakes on its own.
Aim for a session you can finish cleanly rather than a perfect score. Consistently typing at 96 to 98 per cent accuracy is a better base for speed than occasionally hitting 100 and often dropping to 85.
