Studying “by feel” wastes time, whatever the language. Blue builds on proven learning principles — applied identically to English, Spanish, French, German, Chinese, Japanese, Korean and Arabic.
The placement test estimates your CEFR level (A1 → C1) and sets a reachable goal, in the language of your choice. No generic course: you work on what you need.
Vocabulary and grammar come back at the right time, just before you forget. That's long-term memory: you retain it for exam day, not just for the evening.
Mock exams reproduce the format, timing and difficulty of each test. You tame the stress and the pace before facing it for real.
Estimated score, weak spots, targeted recommendations. You always know where you stand and what to review next — no more going in circles.
Record yourself: Blue compares your reading to a native model, scores you and colour-highlights the words to work on. Ideal for speaking, in every language.
Quiz, dictation, matching, flashcards, role-plays: the same word, the same grammar point worked from every angle — recognition and production alike.
A linear, structured path, designed so you never have to wonder “what do I study today?”.
You choose your language and certificate, then take the placement test. Blue computes your starting point and your goal.
