Cute you think pointing out minro errors takes away from the major point.
You mean the bulk of humanity is worse than the very bvest and if you want to teach them math you need much lower standards?Download the text of one of those and come to Skype with me. I finished high school this year and I'm sure I'd score more than that. So would probably half my (old) class. (assumption taken by seeing 2012's problems)
The point I'm trying to make is that average is skewed by so many factors that it's not a good indicator of how people are actually performing.
OMG FLEXI RAID!!
