More about the tags

The English Grammar tree breaks topics down by grammatical category — from determiners to verb tenses and everything in between. Our taxonomy overview explains how we organized it all. The categories are not set in stone— we continue refining them to be as useful as possible.

CEFR stands for the Common European Framework of Reference for Languages — a widely-used standard for benchmarking language ability from beginner (A1) to mastery (C2).

Difficulty Levels reflect the content authors' judgment of how challenging each question is, so you can start easy and work your way up.
