Schools pricing... WOW (Istanbul)

Schooling (Americans) for middle school kids (grades Protected content . .. am I crazy that the prices are straight outrageous ($25k a year per kid)? Are there other options, lesser known schools? Tutors? Group tutoring? Yeesh. I can pay someone to teach my kids math and science and Turkish for that price and still buy a car.

Is there even a decent (not blacklist) $10k a year. I keep seeing Keystone, even though it is far from where I work.

I hate for their "online" option to be my best bet.
