real levels ✦
Friendly on the surface, rigorous underneath
Official CEFR levels — four per language, six for English — the same ones international exams use. You move up by mastery, not streaks.
A1 · Foundations
Greet, introduce yourself, handle numbers, dates and routines. Everything explained in your language.
A2 · Building up
Past and future tenses, travel, work, shopping and everyday exchanges. Everything explained in your language.
B1 · Independent threshold
Opinions, hypotheses, real experiences — with fully immersive reading and listening.
B2 · Upper intermediate
Argue with nuance, follow debates and complex texts, write with the right register. Course 100% in the language you're learning.
C1 · Operational proficiency
Irony, register, extended discourse; demanding texts and audio. Fully immersive course.
C2 · Mastery
Near-native precision, style and cultural nuance. Fully immersive course.
B2 is live in all four languages; C1 and C2 in English.
Immersion grows with you: in A1–A2 everything is explained in your language; in B1 comprehension switches to the language you're learning; from B2 on, the whole course is in that language. Step by step, the language you learn becomes the language you learn in.
