So much depends on personality. Some kids tolerate drudge work they already understand and some just don't. Some would rather fight for an hour than spend 5 minutes doing the work. <shrug> Just how they're built.
The behavior problems seem far more troublesome to me. I really think those issues tend to be sincere cries for help from HG+ kids. Not always, of course--every child is different. But I think the anger and lashing out more often than not are signs that something isn't working, and isn't working in a big way.
Just my NSHO...
