Start English from zero to CEFR A1: letters and sounds, introducing yourself, describing things and places, daily routines, shopping and directions, and reading and writing short messages.
Each lesson teaches one small piece of language through a situation (a classroom, a family, a shop, a street), then practises it in speaking, reading and writing. Young learners and adults use the same lessons; the examples are everyday and age-neutral. The course ends with a "Welcome to my town" project and a short shopping role-play.
