FWIW, my dd12, skipped a grade and was already very young for her grade prior to the skip. Her PSI score was a 94, if I recall correctly. It came out at the 42nd percentile. She's done very well with the skip and her speed hasn't been a major issue. I do wish that she would work faster and it does seem like her homework takes longer than it should, but then again I am a really fast processor, so my estimation of how long things "should" take may be off wink .
