$14,900 for High School.
That is just the tuition... After that you have to add in all the different fees (i.e. technology, transportation, lunch, tutoring if needed, etc.)
It ends up being closer to $20k per high-school student when it's all said and done.
I graduated from there, and honestly it is one of the best educations money can buy. However, when they pester me to contribute to their annual fund, I think about how much they're bringing in to begin with and decide against it.
