Typing Accuracy Test & Weak-Key Practice
Take a typing accuracy test to find the characters you missed in this session and the ones with longer gaps before them. After the diagnostic, choose “Practice these keys” for a focused drill, or follow the typing accuracy practice guide to work on recurring mistakes.
Click the typing area and copy the displayed words, including spaces. Use Backspace to correct mistakes. The attempt ends at the end of the passage; there is no fixed time limit. Corrections do not remove the original error from your accuracy score.

How to read your typing error analysis
Most-missed keys are the characters the passage expected, ranked by incorrect entries divided by attempts at that character. Total errors break ties. For example, two errors in ten attempts at “e” give a 20% error rate. This is a character-level summary; it does not group mistakes into misspelled words.
Slowest keys are ranked by the average time since the previous character entry. That interval can include reading, a pause, or a Backspace correction. It is not a measurement of physical finger movement. The first character has no preceding interval.
“Practice these keys” combines up to six most-missed and six slowest characters without duplicates. The drill uses repeated characters separated by spaces; a selected Space key is represented by “sp” groups. Afterward, return to fresh words to check whether the same mistakes recur.
Overall accuracy uses all character entries, including mistakes you later correct. WPM uses correct characters in five-character units divided by elapsed minutes. See the WPM and accuracy scoring explanation.
