Those labels — *A1, A2, B1, B2, C1, C2* — refer to levels in the CEFR (Common European Framework of Reference for Languages). It's a standardized way to describe how well someone knows a language, especially used in Europe but recognized worldwide. Here’s a quick breakdown: --- *Beginner Levels* A1 (Beginner): You can understand and use very basic phrases. Can introduce yourself and answer simple questions. Example: “Hello, my name is Anna. I am from Spain.” A2 (Elementary): You can communicate in simple tasks and routine situations (e.g., shopping, family, work). Example: “I want to buy a train ticket to London.” --- *Intermediate Levels* B1 (Intermediate): You can deal with most situations while traveling, and can talk about topics like work, school, and hobbies. Example: “I’ve been working as a teacher for three years.” B2 (Upper Intermediate): You can interact with native speakers quite comfortably and understand more complex texts. Example: “I would prefer if we could reschedule the meeting for next week.” --- *Advanced Levels* C1 (Advanced): You can express ideas fluently and understand nuanced meanings. Great for professional and academic settings. Example: “Despite the challenges, we managed to meet our quarterly targets.” C2 (Proficient): Near-native. You can understand virtually everything heard or read and express yourself spontaneously and precisely. Example: “His argument was not only well-articulated but also subtly persuasive.”
