Mention homeschooling to UK parents and they'll likely shudder as they remember those tough lockdown days, but for the Queen, being educated at home was the norm.

The monarch and her sister Princess Margaret were educated by their mother and a governess, Marion Crawford, who they affectionately called 'Crawfie', as well as private tutors. The siblings were the last members of the royal family to be permanently educated at home and neither sister gained any formal qualifications.

However, their knowledge was vast. The pair were taught to read and write by their mother until they were age seven and the Queen later became fluent in both French and German.
The monarch also took lessons in constitutional history from the Vice Provost of Eton, Henry Marten. According to royalcentral.co.uk, the then-princess also learnt about maths, history, dancing, art and singing.

Professor Kate Williams, author of Young Elizabeth, has previously told Good Housekeeping: "The Queen's father had disliked school and her mother thought it was more important to have fun."
She added: "Unlike her father, the Queen was and is very bright and had an appetite for learning as well as a razor-sharp memory."
"The lack of a formal education didn't harm her as she's naturally analytical and something of an autodidact (self-taught), as well as being hard-working - which we know now is just as important as raw brainpower," Kate added.
The Queen also had a role in World War II, when she joined the Auxiliary Territorial Service which helped to repair vehicles.
