We have been asked not to tell him for the next couple of weeks while they iron out all the details amongst the staff! I think that he must suspect something and we did casually mention a one year skip which he wasn't against, not sure if a 2 year skip will seem very scary to him (well it is to me!).
We will definitely be able to tell if it isn't working as DS changes a lot when he is unhappy at school - in the past when he has been bored at school he has been intolerable at home. I think that the higher "base level" of work is really going to suit him.
Doesn't it feel good to finally have some options and make a decision even though on the inside you are biting your nails.
I know once we made the decision dh and I felt more confident in our ability to take on future academic challenges.
My ds is the same way about not coming right out and saying that he is bored or something is off at school but he has specific "tell's" that alert us.
Good Luck please keep us posted.
