Hi Neda,
Good idea to find out if the test score is compared to all gifted kids or the whole group of same aged kids.
I don't reccomend "prepping" but it does seem to be worth explaining the difference between solving every math exquation and reasoning it out. Most kids will naturally reason it out, which is what the test hopes and expects, but a few with the perfectionism thing going will try to solve every problem and then not have enough time for all the problems. It's worth making sure your child understands the difference.
Smiles,
Grinity
