Princess Charlotte, the daughter of the Duke and Duchess of Cambridge, arrived for her first day at school on Wednesday morning.

Charlotte, age 4 and fourth in line to the throne, was dropped off by her parents at Thomas’s Battersea, along with her older brother Prince George who also attends the fee-paying south London school.

Kensington Palace tweeted a video showing the Cambridges completing the school run this morning.

Thomas’s Battersea educates 560 boys and girls between the ages of 4 and 13 and charges £6,429 (about $7,900) per term, according to the school’s website.

Since her older brother also studies there, Prince Charlotte will receive a sibling discount which will reduce the cost to £6,305.
