Training with Koch Method (Total 40 lesson)
First, you try lesson 1 which sends only "K" and "M".
If you get accuracy over 90%, you can step up to next lesson.
Each step adds just one character.
And you repeat it to lesson 40.
Speed should be over 15wpm all through training.
After 40, let's reduce character spacing and word spacing step by step.
1.9 ... 1.8 ... 1.5 ... 1.0
Okay, character/word spacing is now 1.0 which is "real" speed.
Let's speed up wpm step by step.
When you get 90% accuracy for 20wpm, you listen 15wpm easily.
And you can choose more speed or word training.
