The Proficient user level covers 2 levels: C1 and C2 

At C1 level, learners can express themselves fluently and spontaneously, use a wide vocabulary, and can choose appropriate expressions to introduce their comments.

At C2 level, the user's proficiency in the langage is illustrated by precision, appropriateness and fluency of expression.

The Regular course offers the best option for a smooth, gradual learning process, assuring a balanced approach between communication skills, cultural elements and grammar.

All four language skills (oral comprehension, oral expression, written comprehension and written expression) are broached following a well balanced progression.
