This exercise is designed for students of English who need to master English irregular verbs. You can consult a sortable list of these verbs on the Irregular Verb page.
The verbs are grouped by their CEFR classification into seven levels. Level 1 only contains verbs classified as A1. Level 2 contains verbs classified as A2 plus selected words from level 1. Level 2 contains verbs classified as B1 plus selected words from the previous levels. And so on. By reaching level 7, the student will have seen most of the verbs a number of times. Level 7 contains less frequently used irregular verbs not classifed in the CEFR. Complete each table by typing the correct form of the verb in each empty cell. Use the tab key to move to the next empty cell.
