If public schools inflate the marks of the students, why the private students wouldn’t then go to public schools to get better marks?

It's a one off event.

If it weren't then of course private schools might also start giving more generous estimates.

But, also parents might still prefer a better education rather than a higher grade.

FYI public schools are private schools in the UK, the nomenclature is rubbish.
