Wow! That is a high WMI!!! Yes, you are not alone - you have us!

Do you have any of the achievement scores that meet the criteria for DYS? An outstanding portfolio (demonstrating 2-3 years ahead in math achievement) combined with high achievement scores might do the trick. I cannot offer suggestions about the portfolio (both of mine used scores), but others here might be able to offer advice on how to submit a qualifying portfolio.

All the best to you and your DS!
