If you still haven't tried to take a test for it,here's a site:

I got an gross of 45 words per minute,with 27 spelling errors and 7 punctuation errors(which is a lot,but wasn't much focused either).I did the three minute test as duration,and the topic was Laryngoscopy Surgical Report.I think my speed is ok,though,I will take some other tests with higher concentration to see if I can reduce those spelling errors.

So What's your typing speed?
