Prince George has started his first day at Thomas's Battersea school in south-west London.
Here are 10 things you probably didn't know about the young prince's academic facility:
Fees at the school cost £17,604 a year and increase in Year 3.
If George stays at the selective establishment throughout, until the end of Year 8 when he turns 13, the total cost will be £172,116.
2. School Rules
The school's most important rule is ''be kind''. Thomas's Battersea expects its pupils "not just to tolerate but to celebrate difference, including faith, beliefs and culture".
3. Teaching Leadership
"We aim to equip our pupils to lead by example; to be prepared to stand out from the crowd; to be the first to respond to someone in need; to stand up for what they believe to be right; to risk making an unpopular decision, if they believe it to be for the greater good," the school states.
4. Best Friends 'Are Frowned Upon'
It has reportedly discouraged pupils from having best friends in a bid to stop others from having their feelings hurt.
5. Small Class Sizes
Four-year-old George will enjoy small class sizes of about 20 pupils. The average class size for primary schools in England is around 27 children.
6. Learning Ballet
The young prince will be learning ballet - along with French, art, drama, ICT and music, as well as the Early Years Foundation Stage curriculum.
7. Uniforms Are Compulsory
The uniform includes smart, pulled up red socks and navy bermuda shorts.
8. Art Smocks, Swim Hats and PE Kits
George must have a red art smock - which costs from £30 - a swim hat and PE kit.
9. Registering Your Child Early Is Key
Parents are advised to register their child soon after birth to be in with a chance of attending the over-subscribed school.
Potential applicants take an entrance assessment before being offered a place.
10. Organic School Dinners
School dinners at Thomas's Battersea are often organic.
Previous menu choices range from freshly baked courgette, halloumi and beetroot layer slice, to Marine Stewardship Council (MSC) certified pangasius, leek and spring onion risotto, and oven baked beef meatballs with cannellini beans in a tomato and basil sauce with grated organic cheese and fresh crudities and steamed 50/50 brown and white rice.
