Ummm, yes, I really scored zero. I finished, got 6 right, didn't realize I forgot to click submit, and went elsewhere for what apparently was a total of 205 seconds. So, with time penalties, zero points.
But that was the one I thought was a bit high; 700 was where it was at, and only 12 people have done that today.
But then I saw it has been moved down to 200.
