Thank you all for the insight and book suggestions, I will definitely look into getting some of the books. DS loves science too. We subscribe to BrainPoP and he can sit and watch movies after movies on science topics, and sometimes math.
I apologize for writing WISC-III instead of WISC-IV. I think I was thinking of WIAT-III when I typed that. DS took WISC-IV.
Can someone give me a brief description on what happen after you are accepted by DYS. Does it mean that you can contact them with questions? Do they give suggestions on curriculum? We have this forum with wonderful parents who has a lot of experience with gifted kids and are so kindly helping other parents. I'm just trying to decide whether it's better to seek advice here or make the investment to do another achievement test. I have a feeling that his score will be better this time around.
