I have a 1st grader in the gifted program, she was tested in Kindergarten. Like you I wanted to let her have some practice skills with the test so she wouldnt be scared.
She is exceptionally bright but lacks confidence, making her fear tests. She did very well and when I asked her what she had to do she replied 'baby stuff'. That probably was the academic tests. I feel the best way to prepare her is to practice some logical reasoning work sheets, from what I've seen so far this is one of the main assessment areas.
Hope this helps.
