I edit as I go along, and the first paragraph I got really didn't work well for me in that respect, so I spent too much time editing what I wrote (and still got three mistakes).
The second paragraph I got was closer to the words I would normally type I think.
It does depend on which test you take. The Faeri Queene was littered with odd spellings that made me have to double check what I was typing.
I have no excuses on the second test, though.
That's quick. I suppose a touch typing course wouldn't really be beneficial to those of us with bad typing habits. If I thought it would improve my typing, I'd probably have a go at one of those.
