Hi Tall Boys and welcome to the board!
I've got a DS7, too. MrWiggly (his choice of screen name, BTW!).
It sounds like you have a pretty good school for them at this point, if they actually did the testing and then moved the 6 y/o up a grade! That is *way* better than a lot of us have had to deal with! Not the end of your journey by a long shot, but what a great start!
I often have the same feeling and have even been told by MrWiggly that he's smarter than I am. I just try to stay one step ahead

Good luck and glad to have you here!
