Not all activity contributes equally. Activities that require you to produce language freely carry the most weight.

Voice Scenarios contribute the most. Each session is graded 0–100, and the length of what you said adds additional evidence. Longer, natural responses contribute more than very short ones, but length alone does not increase weight without limit.

Practice Questions contribute at a lower level, but the question type matters. Speaking questions carry more weight than fill-in-the-blank, which carries more than multiple-choice. A correct speaking answer contributes roughly three times as much signal as a correct multiple-choice answer at the same CEFR level.

Every level estimate comes with a confidence score. Confidence starts low and rises as evidence accumulates. The confidence score reflects how much data supports the estimate, not how well you are doing. A low confidence score means more activity will sharpen the estimate, not that the level is wrong.

Completing the same question or module repeatedly contributes less than working across different topics. Five different B1 modules provide significantly more evidence than one B1 module repeated five times. The estimate rewards breadth over repetition.

Older activity carries less weight than recent work. Evidence decays gradually over time. A long break will reduce your confidence score but will not reset your level. The estimate always reflects your recent activity more than your distant history.

If you consistently score below 40% on content at a given CEFR level, the estimate treats that level as a ceiling and reduces confidence in any level above it. Improving your scores at that level will lift the ceiling over time.

Your level reflects the work you do in the app, measured against the CEFR scale from A1 to C2.

Scenarios carry the most weight. They test you across many topics and situations, so they reveal far more about your overall ability than drilling a single concept. Modules are useful but narrower. Completing many different modules counts for more than repeating the same one.

Your level is set at the highest point where the evidence is consistent. Each activity adds a little more, so confidence starts low and grows. It rises fastest when you write longer scenario responses and work across varied topics, and more slowly when you repeat the same content. Once you are placed at a level, everything below it is confirmed, and old activity fades slowly, so a break will not reset you.

An A1 speaker handles only the most basic personal information using a small set of memorised words and phrases tied to immediate situations. Speech is slow and fragmented, and communication depends entirely on the other person speaking slowly and rephrasing.

A1 → A2 Go from isolated words and fixed phrases to handling simple transactional exchanges in the real world.

An A2 speaker manages simple, everyday situations, shopping, directions, basic personal exchanges, within a narrow set of structures where errors are frequent but rarely block understanding. Conversation is mostly reactive, coming in short bursts with pauses and reformulations.

A2 → B1 Go from reacting to others to independently sustaining and steering a conversation.

A B1 speaker can navigate most everyday situations at work, school, or while travelling and discuss familiar topics, though with some hesitation. Grammar is reasonably accurate within well-practised patterns, and they can independently start, sustain, and close simple conversations.

B1 → B2 Go from familiar, concrete topics to abstract and complex ideas, expressed with growing spontaneity.

A B2 speaker discusses a wide range of concrete and abstract topics clearly, including technical subjects in their field, without conspicuously searching for words. Grammatical control is high, speech flows fairly evenly, and they take part comfortably in conversation with native speakers.

B2 → C1 Go from competent communication to genuinely effortless expression across professional and academic contexts.

A C1 speaker expresses themselves clearly across general, academic, and professional contexts without simplifying what they want to say. Accuracy is consistently high, language flows almost effortlessly, and they manage conversation skilfully, holding the floor and steering discussion.

C1 → C2 Go from full command of the language system to native-like sophistication, nuance, and stylistic range.

A C2 speaker commands the full breadth of the language, engaging with any abstract, nuanced, or culturally specific topic with precision and a rich idiomatic range. Control is complete and speech is spontaneous and natural, with native-like turn-taking, allusion, and effortless reading of conversational cues.
