Re: use it or lose it.
I don't think you can really lose it, but it can certainly become rusty
. I was in a not very challenging school. I chose a challenging track in high school within the limited options available in my home country. Those 2 lasst years of high school, I began to stretch my mind again, challenging teachers instead of just daydreaming in class, etc. For university, I had to make my brain work again. It was a nice feeling, and it just got some adjustement that I needed to actually study. That happened to a lot of my peers, there were a few lucky ones who had been challenged before hand, they were ready to go. Some never got used to having to work to keep up, and ended up dropping out.
In short, I think it is important to keep your DC mind's actives. If the school continues to refuse accommodations, then he has to work at home, be learning new things.
