You are not alone. I feel the same way with DD. She is 5, and is on track to finish all elementary curriculum by the end of next year. She will be 6.5. It's crazy. I feel the same way with testing. We don't have the money right now, but are planning on trying to test next spring. What if it shows something different I worry, but then I try to remember that what we see is most likely what we get and it's not like we haven't been told what we see is true by others...and I am sure this is the same for you all. She has been seen by a developmental psy and assessed...just not with official iq results, and he threw numbers at me that made my head spin, but then I have to take it day by day. But I do freak when I think of testing and what if it comes back low, does that mean what I and others have seen is not there, should we not grade skip all that we are doing, if everyone wrong. So see, while I have no advice, you are not alone LOL.
