There are boarding schools, schools of the air, etc. Serious parents can move house for catchments, etc.

I grew some 1,500km north of the nearest city and got by .. still managed to hook up with Terrence Tao and Paul Erdős when I got to university and ran a math club. When one of my kids was ready for high school we got a house in the catchment of the only public school with an aviation program so they could build and fly a light aircraft.

I enjoyed going to school with hunter gathers in the Kimberley .. I don't feel they held me back, I did get to learn how to fish, to hunt, to swear in several languages.

Despite a lot fighting at high school, on and off the fooball field, I managed to pick up enough abstract algebra to work on CAYLEY/MAGMA which cracked a few quantum encryption candidates recently, enough linear algebra and calculas to author a geophysical processing suite, etc.
