It takes some adjustment to work out that Year 12 is what I knew

That is actually off by one. The old 5th form is now called year 11,
and the two 6th form years are therefore years 12 and 13.

Year: Age
R: 4-5 (R = reception)
1: 5-6
2: 6-7
3: 7-8 (ex 1st year juniors)
4: 8-9
5: 9-10
6: 10-11
7: 11-12 (ex 1st year secondary/grammar)
8: 12-13
9: 13-14
10: 14-15 (begin GSCE options)
11: 15-16 (take GCSEs)
12: 16-17 (Lower 6th)
13: 17-18 (Upper 6th - take A levels)

Can't remember when this system started, but it was already in use when
my kids were at school in the late 80s and 90s.

Cheers
Tony
