At the C2 level, learners reach a near-native proficiency, allowing them to understand and express themselves in almost any situation with ease. They can:

Understand Almost Everything Heard or Read: Students can easily understand virtually everything they hear or read, including highly specialized and complex texts.
Summarize Information from Different Spoken and Written Sources: They can summarize information from a wide range of spoken and written sources, reconstructing arguments and accounts in a coherent presentation.
Express Themselves Very Fluently and Precisely: Learners can express themselves very fluently, precisely, and accurately, even in more complex situations, and can differentiate finer shades of meaning even in more complex situations.
