You understand the main ideas of complex texts, including a technical discussion in your own field when it is explained clearly. You join a conversation with locals at a reasonable pace, defend a point of view, and write a clear, detailed text. Accent and errors rarely block the meaning.

It is participation: nuance, register, and texts with some density.
