Is there really a difference “in age” for 16 year old to be in class with 15 year olds? It’s about physical maturation for an athlete, not some spiritual awakening or maturity growth. Also, if you repeat at on the Parisi type places you aren’t repeating the same thing. They actually do a lot of cool real world experiences like visiting banks, PT places, restaurants and learn real world stuff like balancing a checkbook.I respectfully disagree. I don't think it's good for a kid to be in a class where he or she is a different age than the rest of the class. It's also not good for a kid to have to repeat the same academic material -- it's boring as hell and likely to turn the kid off to schoolwork. That's why schools these days almost never hold kids back -- it was much more frequent when I was a kid a million years ago. But of course you're entitled to see this differently.
