How can I get grade 11&12 boarding school scholarship in the states?

Answer 1

Almost all the boarding schools in the US for high school grades are private schools, and most have large tuitions. There are a few run by states, such as the North Carolina School for Science and Math, but these are rare.

Therefore, you will need to search for private schools (often called "prep schools") and contact them to ask about scholarships. Some of these schools are quite wealthy and might be willing to cover your expenses if you bring the right "diversity" to the student body. (American schools are very big on "diversity" these days.) The good news is that these prep schools usually provide a top-notch education.
