Nothing really startling. You can't get to be great unless you have inborn talent but you don't need to be a maths genius to complete high school maths.
I find his thing saying the people who consider themselves failures get 85% vs those who consider themselves sucesses get 100%. What about those who got 30%? And if many people are getting above 85% the test is too easy. OK our pass mark is 50% not 60% but people very rarely make no mistakes. Unless the test is multi choice? Then maybe but they aren't used much here.
