Never seen this before. Take a look at Hidden Lake Academy. $84,000.00 PER YEAR, minimum stay 24 months. So, $168,000.00 MINIMUM, but more than likely your kid will not be "ready" to leave at the end of two years. Some stay FOUR YEARS PLUS POST-GRAD ($336,000.00 + undefined "post grad")
You got lucky by comparison. Same results (shitty education, not prepared for the real world, no therapy, etc), but laid out less cash for it.
