Well I learned how to type when I was in 4th grade or so, so its been 15 years of practicing for me. I recently just tested my average w.p.m. out of curiosity since its been so long and was wondering the average from the community as well. In about a minute I made 3-4 mistakes and had an average of 97 w.p.m.
I'm satisfied with my speed, but I tend to still make typing errors often which I've reminded myself to be aware of but still can't seem to improve upon it. I wonder if it's related to the fact that I constantly accidentally right-click my mouse when my hands are resting on it.
