We start High School at 14 in the states.

but don't you only start reception (what you call kindegarten) at 6? We start it at 4 and it carries on like this.

Infant School

KEY STAGE 1
Reception - 4 to 5
year 1- 5 to 6
year 2 - 6 to 7

Junior School/middle school

KEY STAGE 2
year 3 - 7 to 8
year 4 - 8 to 9
year 5 - 9 to 10
year 6 - 10 to 11

High School

KEY STAGE 3
year 7 - 11 to 12
year 8 - 12 to 13
year 9 - 13 to 14

KEY STAGE 4
year 10 - 14 to 15
year 11 - 15 to sixteen

Then we have the option to go to sixth form for a few years, go straight to college or just leave and get a job.

So I was wrong, we start high school at 11.

i am in 7th right now.....

so by the time i am in high school i will be on my way to 15

Ha! I'm in year 9 at the mo. That's the equivalent of eigth grade. We learn everything a year earlier.
