For us, the IQ score enabled our son to attend a charter school that only admits kids with an IQ above X. The school itself did not add that much to his knowledge. He had some bad teachers and some v good teachers like every other school. The biggest benefit was he was surrounded by a great group of interesting kids for three years.
He is interested in STEM and history and as he never really learned a lot in school we supplemented his learning with AoPS and other online resources. He also enjoys academic competitions, primarily due to the kids that are typically involved. I do not think we did things any differently based on his IQ. We simply always tried to keep him interested and challenged.
His IQ was tested at 145 but he has performed much better than some that probably have higher IQs given his work ethic and level of interest. There are also some of his friends that regularly beat him in some of the math competitions, typically they have parents that are very highly educated in math. Math competitions are a great way to keep him grounded.
