Switzerland's Institut Le Rosey is considered to be the most expensive school in the world, costing about more than $113,000 a year.
Those who've attended the boarding school located in Rolle and Gstaad, Switzerland are often given the nickname: Roseans.
"Old Rosean" is the official name used to describe alumni. And Arabs are among them.
Here's a look:
1. King Fouad II (Egypt)
Egypt's King Fouad II, the son of deposed King Farouk, attended middle-school in Lausanne and then attended the prestigious Le Rosey international boarding school where he obtained his secondary school Baccalaureate diploma.
He then continued his studies at the University of Geneva before moving to Paris where he started a real estate business.
King Fouad II, who was technically the country's last monarch at younger than 1 years old, was forced out of his native country before his first birthday.
The king eventually married a French woman who was later given the nickname "Queen Fadila of Egypt" ... and the couple had three children together before getting a divorce.
He eventually moved back to Switzerland after going into deep depression.
2. Ghida Fakhry (British-Lebanese)
Fakhry is an international broadcast journalist and contributor to the HuffPost with over 20 years of experience in the industry.
Fakhry studied at Le Rosey.
She received a French baccalaureate degree before completing her undergraduate studies in London.
She continued her graduate studies at the SOAS, University of London where she earned two Master's degrees: one in Near and Middle Eastern Studies and another in International Relations.
3. Emad "Dodi" Fayed (Egyptian)
You may know Dodi as the son of Egyptian billionaire Mohamed Al Fayed and Samira Khashoggi (sister of Saudi billionaire arms dealer Adnan Khashoggi).
You may also know him from his romantic relationship with Princess Diana of Wales, with whom he died with in a car crash in Paris (1997).
But, there's more to Dodi than just these bits of information.
In 1968, Dodi's father, Mohamed Al Fayed, sent him to Le Rosey for its three-month skiing term in Gstaad.
Dodi, who was 13 years old at the time, spent one year there before leaving, according to Philippe Gudin, director general of the school.
One Le Rosey graduate said that the 13-year-old found the school "really tough."
He later attended the Royal Military Academy at Sandhurst, according to The Independent.
4. Khaled Juffali (Saudi Arabia)
The Saudi businessman is the son of Ahmed Abdullah Juffali, the founder of one of the kingdom's largest companies: E.A. Juffali and Brothers.
Juffali was educated at Brummana High School in Lebanon and at Le Rosey in Switzerland.
In 1979, he earned a bachelor's degree in Business Administration from the University of San Diego, California.
