I should also add that these articles are legitimate or legitimate style articles that are actually interesting and fun to type (such as outtakes from Ben Franklin's biography, to scientific articles, many topics) unlike those boring, fake ones that usually are in place on typing programs (which make you feel like you're back in elementary school) and you can even import your own text. This is a great practicing tool for after you learn all the keys and want to stay sharp. Mavis Beacon 20 (I have only tried the platinum edition) also has a new practice feature which I haven't found anywhere else, where you can choose from a huge selection of articles where you just type right along with the text while the text you type appears in the lines in between the text to type (no looking halfway down the screen to see mistakes), errors appear in red and make a little noise to let you know that they have occurred.
