All Linguapolis courses have a certain Linguapolis level, for example: Level 1, Level 2, etc. Each Linguapolis level corresponds to a certain level on the CEFR scale.
The CEFR has six levels: A1 and A2 (basic user), B1 and B2 (independent user), and C1 and C2 (proficient user).
More detailed descriptions of what you should be able to do at each level in terms of listening, reading, holding conversations, speaking and writing can be found on this webpage.
For more information about how the Linguapolis levels correspond to the CEFR levels, see the ‘Levels & Common European Framework of Reference for Languages’ sections on the following pages:
