Wow Uni is real cheap in England. You'd be in a big shock to go to Uni here. A fairly good Private school for little kids is more than that here in the USA. Private school for high school is 2- 3 times that a year and a fairly good Uni is 2-5 times that. You don't even want to know what the Ivy League Unis are here in the USA. Oxford is an excellent School too - and that is amazing that is all it costs in England.
One of my best friends kids just started High School which is a private school, not a boarding school and my friend had to pay almost 25,000 dollars for her daughters first year. It is a good private school but far from the best.
My granddaughter just changed Universities as she had a two year scholarship where she was going, but could not afford to pay full tuition there without a scholarship for the next two years, she is studying Nursing, and it is an okay Uni but not a highly accredited one, and it is still costing her almost 30,000 a year. The one she was at and wanted to stay at she could not afford was nearly 50,000 a year.
