What it is: A global scale that describes English ability from A1 (beginner) to C2 (near-native). What it’s for: Choose suitable books, videos, and goals. Example: A2: “I can talk about daily routines.” B1: “I can explain opinions.”

• A1 (Beginner): Basic phrases, introductions, very simple sentences.
• A2 (Elementary): Daily topics, simple past/future, short conversations.
• B1 (Intermediate): Longer conversations, opinions, work/travel topics.
• B2 (Upper-intermediate): More complex texts, debates, clear writing.
• C1 (Advanced): Flexible language, nuanced meaning, academic/work.
• C2 (Proficiency): Near-native understanding and expression.

• Pick content slightly above your level (e.g., B1 learner uses B1–B2 materials).
• Track progress by what you can DO (speaking/reading/writing tasks), not only grammar.
