An introduction to the British system for beginners: primary and secondary schools, the subjects, the uniform, and the after-school clubs.
The British school system has a vocabulary of its own - primary and secondary, terms, uniform, clubs - and a learner who has not met it cannot follow a conversation about schools at all. This video supplies it at A1-A2, moving from the types of school to what happens inside them.
Uniform and after-school clubs get particular attention, since those are the parts that differ most from what students elsewhere are used to and therefore the parts that generate discussion. Two minutes, and it pairs directly with the videos on schools in the USA and schools around the world.
