Advanced English learners often reach a plateau where their English is good enough for most situations but still does not feel native or fully automatic. Breaking through that plateau requires practice on the specific things that separate B2 English from C1 and above: idiomatic language, nuance, humor, cultural references, and the ability to discuss complex ideas without simplifying them.
WHAT TO LOOK FOR
Idiomatic and colloquial English
Advanced fluency means using and understanding idiomatic English naturally. Phrases like it goes without saying, a lot hinges on this, or cut to the chase appear constantly in professional and casual contexts. Practice using them until they are automatic, not conscious.
Nuance, tone, and register
Advanced English speakers shift register between formal and informal contexts seamlessly. Practice the same idea in three registers: casual, professional, and formal, until you can switch automatically without thinking about it.
Complex argumentation and discussion
Being able to argue a position clearly, defend it against pushback, acknowledge counterarguments, and change your position when warranted: these are advanced speaking skills. Practice intellectual discussion in English with Lucy OS1 at a high level of complexity.
