@sushiritto , your child is one of the lucky few, and deserves all the credit in the world. I can’t be certain, but I am sure your kid seemed like an amazing fit to the Admissions committee in Ann Arbor. What I am certain about is that the only clear way to differentiate yourself from the pack is through the essay–provided that you are part of the pack in the first place (top grades, scores, ECs, etc.)
With regards to the sports, we all know, however, that there is only one sport and one game that matters.
