Didier specializes in French language books for schools, splitting neatly into two strengths: general classroom instruction and dedicated exam technique. Edito and Génération serve teen and adult learners, Tip Top! and Saison are built for younger classrooms, and the Le DELF – 100% Réussite series focuses purely on exam preparation, a combination that lets schools run standard curricula and DELF prep side by side.
