You're really not doing yourself any favours with that post.
I don't care. Its the internet.

You're really not doing yourself any favours with that post.
Especially since Ofsted exist and their reports are public knowledge, allowing you to avoid the dire schools.
That is part of the problem.
Why does "ticking the right boxes" make it a good school?
why do we teach children about the details of geography or biology if they are not going to go in to that field?
As for social aspect, unless you live in a nice area they are not going to benefit socially from the other children at school, any more than they would if they were to attend groups or sports clubs and similar.
To add to what Zethor just said, it's also important to come into contact with people from a range of backgrounds. Limiting your child's experiences to only meeting people from a 'nice area' isn't beneficial to their development.
If I were to home school, I can certainly say they'd still be doing recognized examinations.
From my understanding this is strongly encouraged, certainly here it is.
lol
Grammar nazis do make me laugh when they use the lack of it as some sort of benchmark of intelligence
Some of the greatest minds to have ever walk this planet had shocking grammar!!
Albert Einstein
Alexander Graham Bell
Nikola Tesla
Michael Faraday
James Clerk Maxwell
Pierre Curie
Willem Johan Kolff
Alexander Faludy
For example geography, why do we teach children about the details of geography or biology if they are not going to go in to that field? forcing a child to memorise all the labels to the cell for example is pointless because its not used in life unless you go in to that field and then if someone wants to know about that they can look it up when they get older.
Schools may have an outstanding OFSTED report due to bringing many lower ability children up to standard, but that doesn't help a parent with a high achieving child.
My worry with home schooling would be a lack of understanding of good teaching practice, AFL strategies, exam technique, controlled assessment requirements, etc.
You don't teach like this, you teach to how the child wants to learn.
