This is a http page so will work with any of the web browsers. It uses the Farnsworth method. Characters are at 25 wpm but spaced out for speeds from 5 to 25 wpm in two wpm increments.
The beauty of the Farnsworth method is you don’t have to relearn the sounds / rhythms of the characters as you increase your speed. You just shorten the spacing.
Each speed directory has six sets of practice materials. The first three are sentences with an increasing number of characters and the last three contain all of the characters and punctuation in five character groups. That’s how my Elmer, W7CHN (sk) taught me. He actually got me to 60 wpm!
