I've read about this fact before. Most persons like to look at themselves as above average. Of course, this is statistically impossible to be true. I don't remember the reasons that were mentioned.

We have a system of rating people in math and language in high school. I remember I scored better then 80% in language and better than 90% in math. I doubt if these scoring systems are very effective since many didn't take them seriously, so they claim.
