learning how to type fast

These days my sister is learning how to type quickly. I used the game that I played to teach me how to type fast to her. I first showed her on micro word. But she did not like it. So I used the game I think she did well on them. But every time she passed a level she did not use what she learned on her last levels she only uses what she is learning on the level she is on. But she does well.
