What to do when you already know how to type without looking at the keyboard and you have mastered all the letters, but your speed isn’t the best? You should definitely further improve your typing speed on TouchTyping.guru.
For that you can use our typing speedtest which by default generates words containing the letters that you already wrote erroneously or you had the significant delay before correctly typing them. Make sure to have this option checked in the configuration. The program calculates your typing statistics for each letter and then uses them to generate the text. Test mode to check typing speed is described closer here.
