Found this via SimpleBits. I took the quiz and scored a 16/20. I’m giving myself a B minus for that one. And a slap on the wrist for not living up to my intensely unrealistic design standards.
Anyway, the ones I found to be most difficult were all capitalized and had fewer letter combinations; also I was unsure of a few of the uppercase forms. I need to brush up it seems, or learn to identify certain typographic features better.
One or the other.
