Hello. I'm from Portugal and i'm doing a work about your programme of physical education. I need to know how many hours of PE do student have in the diferents key stage, 1, 2 ,3 and 4. I read that children could have education at home, instead of having in school, is it true? In what age children start going to school? In stage key 0, what are the ages? Could anyone help me, please? Thank you very much.
