After many months of online learning, schools in Britain are also expected to open soon.

The school of Princess Charlotte and Prince George, Thomas's Battersea, will also reopen this week.

Princess Charlotte will go to first grade and George will go to third grade. Although everyone knows the two little ones as 'Prince' and 'Princess', they will not call them that in school, but in royal terms by their classmates.

Princess Charlotte is thought to have used her parents' title, 'Cambridge', as her last name at school, along with other members of the Royal family, including Prince George.

Thus, the little princess is likely to be known as Charlotte Cambridge by her schoolmates and George will be George Cambridge.

But in addition to their familiar surname, George's friends have another nickname for him. A source told Vanity Fair that George is known as "PG" at the school, Prince George - a short form of his official title, George Alexander Louis - His Royal Highness Prince George of Cambridge.
