The levels of Lerni courses reflect the principles of the Common European Framework of Reference for Languages (CEFR). This system allows determining the level of foreign language knowledge in a specific classification, assessing skills in speaking, listening, reading, and writing.

We will refund the entire course cost if, after at least six months of active use, your knowledge of the chosen language does not improve by at least half a level on the CEFR scale. It is necessary to log in to the course at least 4 times a week for a total of 1.5 hours or more during its duration. Remember that each learning session must last at least 10 minutes.

During a 12-month period, it is possible to have 4 weeks where this requirement is not met. The material you study must correlate with the level determined by the placement test.
