This course isn't an exam prep program. There are no sample topics, no mock tests, no DELF- or TEF-specific methodology.
That said, it trains exactly the skills these exams measure:
Listening comprehension (in every exam): the core of the course. 60 dialogues at natural speed, dictation, comprehension quizzes.
Speaking (DELF, TEF, FIDE): pronunciation with word-by-word feedback, plus Jean, Elisabeth's assistant, and the role-plays to get you practicing out loud.
Reading comprehension (DELF, TEF, TCF): the synced subtitles, contextual vocabulary and flashcards build up your reading vocab.
Writing (DELF, TEF): the dictation and summary exercises train you to write in French.
The FIDE (Switzerland) is built around everyday situations (work, the doctor, the town hall), exactly the kind of conversations covered by the 60 dialogues.
Bottom line: the course doesn't prepare you for the exam format, but it builds the skills the exam measures.
