What are private high schools in France like?
In France like anywhere else there are different types of schools: the catholic schools aren’t all the same and the publics aren’t either. Just look at the program, the school, surf the website, contact people who attend the school. Just know that public schools are as good as private ones (in France), once again it all depends on the school you’re planning on going to. There are all kinds of prices but some private schools are affordable. Sorry but I can’t generalise considering there is no answer to your question, every school is different, the prices are various and so are the religions.
