High School education and Madinah University in Saudi Arabia

[Angelic Light]

Assalam-O-Alaikum my Muslim brothers and my Muslim sisters.
Hope you all are doing well by the grace of Allah.

First of all, I want to tell that English is not my first language, so please try to understand my words.

I have a question regarding high school education in Saudi Arabia and Education in Madinah University.

1. Is High school education in Saudi Arabia free?

2. Does Saudi Arabia provide CIE (Cambridge International Examinations) Exams?

3. Does the University of Madinah have a high school of its own?

JazakAllah Khair (May Allah reward you all with goodness)
