Where is north writing school located the Paul Revere went to?

Paul Revere did not attend a school called "North Writing School." There is no record of such a school existing.

It is likely you are thinking of the North Writing School in Boston, which was a school for boys, but it was founded in 1789, long after Paul Revere's lifetime (1734-1818).

Paul Revere received his education at the Boston Latin School, a prestigious grammar school that was founded in 1635.
