Mmm. In the land I'm from, there's public - that's to say government funded - and compulsory education between the ages of about six and ending at about fifteen. Those are what you'd call Primary and Junior High School. However, there's also a school below that a lot of parents invest in from age three to six, Kindergarten. And finally, of course, there's high school. Age fifteen to eighteen. You have to pay for that, but most of the nation guns for it as well.

[a beat] Of course, if you're really smart - and have the money - you can then go on to university for the next four or five years, and then if you're really smart, on to graduate school for another three.

It almost sounds silly, putting it like that, but to me, it's "normal"
