ب2 is a term used in the context of language proficiency, specifically referring to the second level of the Common European Framework of Reference for Languages (CEFR). At this level, learners can understand the main ideas of complex texts and interact with a degree of fluency and spontaneity. They can also produce clear, detailed text on a wide range of subjects. Achieving ب2 proficiency indicates that a person can effectively communicate in various situations, such as work or travel. This level allows for discussions on familiar topics and the ability to express opinions and arguments, making it a significant milestone for language learners aiming for advanced skills.
