Congratulations! That is awesome. I am sure you are just proud of him for competing. My daughter is 8 and just participated in a national 4th grade math contest. She was a little nervous because I think she thought I would be disappointed if she didn't do well. I told her I was just proud of her for participating and it didn't matter how she did. Well out of 16 kids at her school that took the test she got 2nd place. And like your son she is happy as a clam. Once again congratulations. I know how proud you must be.
