An endurance test
Ten minutes is where focus and posture really matter. It is good practice for transcription, captioning and long data entry shifts, and for some civil service tests.
This 10 minute typing test starts on your first key and stops after ten minutes. You get net WPM, accuracy, raw speed, consistency and a chart of every second.
Around 40 wpm is average. 60 wpm or more is good for most jobs, and 80 wpm or more is fast. Keep accuracy above 95%.
Fatigue and lapses in focus build up. A drop of 5 to 10% from your 1 minute speed is normal; steady breathing and good posture help.
