I'm assuming that this is not counting kindergarten then? Because where I'm from, children first go to school when they're four or five, depending on their day of birth.

Well yeah. Kids typically enter kindergarten at 4 or 5, but that's kindergarten. They don't enter what we call "first grade" until [i]after[/i] kindergarten.

As an American, I will acknowledge the fact that there are a lot of things about this country that don't make any sense. I don't blame you guys for getting confused. I remember spending a lot of time as a kid wondering why "first grade" was labeled as such when it didn't actually come first.
