only) the most highly able math students beginning when they are as young as 4th grade. The organization�s mission is to identify and instruct the most promising future scientists. At least in the St. Louis area, far more than 1 in 1000 kids qualify for the lessons based on their results after a battery of math achievement, math aptitude, logic and reasoning tests. Many graduates of this three-year program do test into pre-calc as freshmen when they enter either public or private high schools and continue on to prestigious universities.
I wish I had known about it earlier for my son.
Kristen, I had thought this might be a good home school curriculum for your son. I don�t know if you can buy the books anywhere though.
