King Charles is officially his former secondary school backer.

On the anniversary of his coronation, the British monarch accepted patronage at the Scottish institution Gordonstoun, where King Charles attended secondary school, the BBC reports.

King Charles reportedly attended the institution from 1962 to 1967, describing his time at school as "absolute hell."

Monarch's time at school was depicted in the Netflix series that hit The Crown. In the second season, the young King Charles is seen to be instantly miserable upon his arrival - he is bullied by his former classmates, struggling to learn and adapt to the overall lifestyle of the All-Boys institution and not as physically fit as his peers.

It is even rumored that King Charles called the school "the Korditz of the quilt."

Still, the monarch only spoke fondly of his time in secondary school when discussing it in public.

"I am always surprised by the amount of corruption told about Gordonstoun and the careless use of the ancient cliches used to explain it," King Charles said in a speech to the House of Lords in 1975.

"It was tough in the sense that it demanded more of you as an individual than most other schools, both mentally and physically," he continued at the time. "I'm lucky in that I believe it taught me a lot about myself and my own abilities and disabilities. It taught me to accept challenges and take the initiative. Why else do you think I am brave enough to stand up before your lord now?"

In a previous interview, people and historian Robert Lacey, the late Prince Philip, said that "it is described as cruel to send (Charles) to school."

"When Philip was there, he found hardship, climate and rural challenges uplifting," Lacey told the publication at the time. "By the time Charles was there, the school had become a much more conventional private school. It's a poignant, powerful story."

In a statement posted on Gordonstoun's website, the school's leader said the institution was "very proud to be the first senior school to educate the king and proud to note how the years King Charles spent here nurtured his love."”
