Summer holidays are officially over for all schools in the UK.
If you live in Scotland or Northern Ireland you may have been back in school for weeks now, whereas most children in Wales and England headed back to the classroom last week.
Some of you may have been super excited to head back to see your friends and teachers, others might have felt nervous especially if you've started a new school or moved up to secondary.

The summer holidays might've meant playing outside, visiting family, eating ice cream for lots of you, as well as having a break from schoolwork. But as the new school year begins, pupils must return to the classroom.
Heading back to school means uniforms at the ready, packed lunches prepped and catching up with your friends.
