Level: B2-C1
Advanced path — precision and polish
You already communicate freely; this path is about the last 10% — the vocabulary, punctuation, and phrasing that separate fluent from native-like. Six steps, heavier on reading and writing than the earlier paths. Take them in any order you like, but the vocabulary steps pay off first — and your progress appears right here as you go.
