A1, A2, B1, B2 Scenarios

A1, A2, B1, and B2 are levels used to categorize language proficiency, often in the context of the Common European Framework of Reference for Languages (CEFR). A1 and A2 represent basic users; A1 is beginner-level, capable of simple interactions like introducing oneself, while A2 can handle everyday tasks such as shopping or asking for directions. B1 and B2 indicate independent users; B1 can manage more complex conversations on familiar topics, and B2 can understand main ideas of complex texts and communicate fluently. These levels help assess language skill development from beginner to advanced.
