Just tell her when she makes 99th percentile that she should have been 100 (those percentiles always confused me. It always seemed 100 should have been the highest. Is there a 0th percentile?)
I dunno... but I was always in the 99th or 98th... no indication of intelligence... I just test well... multiple guess is muh specialty...
We had parents at the Catholic school our kids attended that used to argue with the principal about why their child should not have been in the 99th percentile because they didn't get any wrong answers. She had to explain carefully that their kids WERE the 100th, that 99% were BELOW them. Took them a bit to process that. ;o)
