OK, I know about 'lower' and 'upper' 6th (though don't really understand why you now go from Y11 to the lower sixth...)- but I was listening to CE on R2 yesterday a.m. and he was asking about a school reunion of was it the upper fourth in 1965 ish! But the point is, what was the lower fourth? Why were the forms called this, what was the historical reason? Was there an upper fourth? Was movement from lower to upper automatic? I recall being issued with books like an atlas in the first form (yes) of a GS in 1973 whose previous keepers had been in the upper third or lower 5th, too.
I believe my dad told be that you started GS back in the early 1940s straight into the third form for some reason- but at 11, surely, as it was very much the 11+ back then.
And do you now start real public school at 13 into Y9? (disregarding the 'Shells' & 'Remove' year group names at was it Harrow?!)
Anyone know?
