My own version of the answers. These only apply to England, Wales and Northern Ireland - Scotland has a different system.
Here they are called either forms or years, and run from R (reception) to 12. Year twelve covers the last two years of secondary school, presumably because they don’t want the bad luck of ‘year thirteen.’ ‘Primary school’ is from receception to year 6 (age 11), and secondary school is from year 7 to year 11 (age 16), with some schools also having a year 12 (many pupils transfer to a further education college at this age).
(There are a few places in the east of England which have a slightly different system, but this post is long enough already).
The law states that from the term following a child’s fifth birthday, the parents are obliged to provide some sort of full time formal schooling. This can mean home schooling, but only if they can prove the child gets the same standard of education as they would in school. In practice, most children start school part-time a year earlier, the term in which they turn four.
Mandatory schooling only applies to age 16, but education is free till age 18.
RE is mandatory in all schools, religious or not, until the age of 14. From then on it’s optional. However, except in certain denominational schools, the RE is not focussed only on Christianity, but studies all the other world religions such as Islam too, and the classes are not an attempt to indoctrinate the child into any religion.
There’s more specialism in the curriculum in England and Wales than in most other countries. For example, while a student may take 8 subjects for GCSE (General Certificate of Secondary Education, the individual subject-based exams you take when you’re 16), they then take only three or four at A level (advanced level), or a vocational course such as mechanics. This is all changing now though, and we’re moving more towards a baccalaureat system.
The only other unusual aspect, which you probably know about, is the prevalence of school uniforms. All state secondary schools have some sort of uniform, and these days most primary schools do too. Parents like them, and the kids don’t seem to mind either.
Central government provides the funding through money raised from taxes. Most of this is distributed to the local education authority, and they spend it according to certain guidelines.

Yes, they’re elected by the parents of the pupils (those who bother to vote), and they are called the governers of the school. They’re not as powerful as school boards in America seem to be.
**
In most schools, yes, but not all.

No, they’re not connected at all. I don’t know where scouts and guides get their funding, but it’s not from schools.

I don’t know, do you?
