I really don't remember about the High School equiv. I tend to view those Woodck-Johnson type scores with a grain of salt. So maybe she really means high school level work?
I think you'll enjoy the book is you can get it through Library Loan. I think you are going to enjoy the YSP, particularly the homeschool list, but it's good to know that not all the kids there will be Level 5s like what you are used to, many will be level 3 and 4. Brace yourself, ok? I'm hoping you'll find a place where you feel totally at home, and YSP is good because the Parents there really "get" level of giftedness, even if their kids aren't level 5. KWIM?
