I actually cannot remember much of the books I was told to read in school.
Lots of Molière, for sure. Somehow I managed to completely avoid the other French Classic playwrights (Racine, Corneille...)
Other, later playwrights (Marivaux...)
Camus: L’étranger.
Flaubert: L’éducation sentimentale
Montesquieur: L'esprit des lois
Baudelaire: Les fleurs du mal (not sure this was required reading, though it was definitely recommended, and I certainly studied some of the poems in class)
Borges: Fictions (short stories collection - translated from Spanish of course)
I'm sure there were plenty of others, but I cannot remember them.
(Oh yes, I'm French
)
