I'm curious about why there's always a question about coudre, moudre and hair in the C1 tests. I understand that they're irregular and need to be learnt, but the questions are always in the present tense, and it seems pretty straightforward for C1. Wouldn't it be more appropriate to make them e.g. A2, and include a wider range of irregular verbs? I feel there are other questions that would be more appropriate and useful for C1.
Not complaining :-), just curious.
