Private school give the best education and generally do not follow the national curriculum (it’s more stretching) e.g. sometimes in a private school you would be doing year 9 and sometimes even GCSE maths in year 7 according to the national curriculum. Public schools do not have high education levels, there are more bullies because those who attend these schools are generally from a lower class family than private school students. Catholic schools are in between not as high level in education as private schools and also not as low as public schools. Less bullies the public, slightly more bullies than private schools (generally!).
Hope this helps! : )
In my own experience i found out that Catholic school teachers care more for their students than in a public schools, rules are more strict but i guess that is good.
Private school you have to pay. Public school you don’t.
It isn’t always better though.
In other words (as a public schooler myself) Private = posh
