These are the old French national exams, like the ones you take in a language center. So you can practice, either to prepare for a real exam or to see what your level is.
ATTENTION, these exams are taken here after each dossier, but they have been created for a completed level; this means that all A2 exams are for a completed A2 level and the same applies to B1 and B2 levels.
So don't be discouraged if you don't pass an exam completely after the first few files.
