CEFR Levels Explained: A1 to C2 and What They Mean for You

What does B2 actually mean? A plain-English guide to CEFR levels, IELTS equivalences and realistic timelines to move up each level.

The six levels

A1–A2 are basic users, B1–B2 independent users, C1–C2 proficient users. Most universities require B2 (IELTS 5.5–6.5); competitive programmes ask C1 (IELTS 7+).

How long does a level take?

With full-time study (20 hours weekly, like ACE's Intensive English Programme), one CEFR level typically takes 8–12 weeks. Part-time learners should expect roughly double.
