I don't understand what info this gives either. DS was given the 2-5 version and scored almost 260 on math but my understanding is 260 is the ceiling and 246 is the 99th percentile for his grade so I don't know what that means about how high above grade level he is, or how high above the 99th percentile. Pretty useless, IMO, other than it telling us he is advanced which we already knew.
