Call me a dunce if you will but I don't get the American schooling system. I do watch all American based TV shows but I still don't get it!
Here's the British version for anyone who wants to compare.
Nursery school: Kids start around 5 years old, and start the "Kindergarden" year (I can't remeber what we call it, will tell in due course) and then Year 1 and Year 2.
Primary school: Years 3 - 6. Kids take SATS exams at year 3 and 6 to show how good the school is. (Note: some catholic schools merge nursery and primary school together, so you stay at the same school for 6 years!)
Secondary school: Years 6 - 11. Kids take SATS exams at year 9 and learn for GCSEs (General Certificate of Secondary Education) in year 10 and 11, which are there main qualifications.
College years: Dependant on their GCSEs, Kids can take A levels at Years 12 and 13. Kids can take resits for GCSEs and A levels if the kid wants, but you can only stay in College for 3 years (I think).
University: You get UCAS points (No idea what UCAS stands for, will find out in due course) for each A level you get. If you get enough you can go to university for as long as you wish and get a degree in any subject you had studied for.
That's about it, the British University flows the same way as American Universities. Masters, Phds Etc.
