Meet Anna Cochrane, your teacher. What you’ll learn at C1
Every chapter is mapped against the Council of Europe’s C1 descriptors.

Express yourself fluently and spontaneously, without obviously searching for words, even under pressure or on unfamiliar ground.
Understand nuance and subtext, in speech and writing, even when the meaning isn't spelled out directly — because every video lesson is taught by a real teacher who shows you how implication and tone actually work in English.
Handle complex, sensitive conversations — give and respond to criticism, evaluate an argument, and hold your own in a professional or academic setting.
Read specialist material outside your own field and follow it accurately, from academic writing to detailed news analysis.
Write with real precision — structured essays, reports and professional communication, matched to whoever's going to read them.
Stay hooked by a genuinely sophisticated story, built for someone who wants more than beginner-level stakes.
