The idea is to bring together in one book all curriculum subjects: French, Maths, English, History-Geo, Life sciences, Physics. There are also options for exploration or teachings: SES PFEG (Management), introduction to philosophy.
Each chapter is processed on a double page with the current left and methods / exercises right. The contents are those of Bordas handbooks, so it remains the textbook with its strengths (the synthetic side) and faults (too many simplifications sometimes).
We all agree that nothing can replace classroom work and lessons with a teacher. This kind of work can help and reassure students (and parents) who want to do more, or who wish to revise otherwise.
