Our online English course is structured in 16 levels. A free test  at the beginning of the course will  determine your level of English proficiency.

If your actual level is C1, you will be automatically redirected to the educational content specifically designed for people of your language level.

C1 Level

The C1 level is the fifth language level of the Common European Framework of Reference for English.

At this level, you should be able to understand:


Long speeches about abstract subjects of relative difficulty


Long texts with hidden meaning


Complex vocabulary not necessarily related to one's discipline


Once you have completed our online C1 English courses, you will be prepared to move on to the next level.

C2 Level

The C2 level is the sixth language level of the Common European Framework of Reference for mastering English.

At this level, you should be able to:


Understand any type of speech.


Interpret abstract texts and literature (even if they are complex)


Communicate with fluency, similar to a native speaker


Our online C2 English course will help you reach this maximum language level, enabling you to interact with native speakers from any English-speaking country.
