blue: I am thinking that is the approach that will work best for DS in high school. I don't really think IB is going to be a good route for him (that's the track, typically, for kids in his program). He is not a high energy kid and fatigues easily, doesn't like a lot of busy-ness (unlike DD, who craves more, more, more).
So now we have to get through 7-8.

Next year he gets to take two electives that will be exciting for him. Maybe just a little maturity will help? I've never been a boy going through puberty and not sure how it affects boys, emotionally.
I know his future is important but the now is pretty important, too--nobody knows what the future holds, anyhow. Balance sounds like a good approach.
