My DS had a few suggestions for some of the first few questions.

-Allow for a Mixed Race Option or allow for a multiple selection

-The grade level only goes up to 12th grade, allow for a "University" option (he's 16 and a Senior at a State University and you did say "performing 3 or more grades above level" and he would be a Junior in High School this year in our local public school ).

-For the years ahead description, if you're ahead in multiple subjects it is hard to describe which one you're ahead in the most. (e.g. what would a computer science algorithm class fall under?)

He said, other than those lead in questions, your comparison questions were simple to understand and select.

Looking forward to your results.
