There is a free online typing test that you can utilize if you ever need to know your average WPM (words per minute).
Here's the link: WPM test.
I googled typing tests and found the one mentioned above to be the most user friendly.
You know, just in case you ever get really bored and want something mindless to do...or you want to impress your friends by telling them your WPM typing speed...or you need the information for a employer...
Whatever reason you have, this was just a friendly, random, FYI.
