Yes, we had results like that and I had the same reaction which faded over several months. With testing for several children now done I can second what Polarbear says. The tests are meant to drill down to areas of weakness, which in our case with more than one child meant several scores in the low single digits or fraction of a percentile score. I really value that information, know now that some of it can be changed and accept that the 99.9 percentile score and the and the 0.3 percentile score can with effort (mostly) peacefully coexist in the same child.
