What I don't understand (being "of an age" and having no sprogs) is all this Year 9, year 12 stuff.
When I was a lad (yawn), it was class 1 to Class 4 infants, Class 6 to class 10 juniors then 1 to 5 in secondary education - then there was sixth form for 'A' levels.

Confused as ever, no idea about the Spanish system either, with it's BUPs, COEs and such mularky.
