That was far better, it doesn't take much effort.
In the UK schools go:
Reception (4-5)
Year 1 (5-6)
Year 2 (6-7)
Year 3 (7-8)
Year 4 (8-9)
Year 5 (9-10)
Year 6 (10-11)
Then you move to secondary school.
You actually start school the term in which you're five years old, either beginning of September, or beginning of January, So if your Birthday is 1st September, you are five when you start (my daughter's is the 4th September), but if your birthday is 31st August, you're 4 throughout your entire reception 'year', and start the previous January.
Certainly in the school my wife works (as a Teaching Assistant in Reception) they teach the kids to read and write in Reception, with some every year attaining year 3 or 4 standards. Some schools though treat Reception as Nursery (pre-school), and don't really teach them at all - it's why our local school has a waiting list
