The floor is the thing to understand
DELF is passed on an overall mark, but every paper carries a hard floor: fall below it on one paper and the whole diploma is lost regardless of the total. For a candidate whose French is uneven — strong speaking, slower reading — that floor is the real obstacle, and it is the reason reading practice is worth prioritising even if it is not your weakest-feeling skill.
FEI describes the task uniformly across levels — read documents and answer questions — and does not publish per-exercise question counts or a typology on the level pages. This page prints the published duration and marking with their source and points you at the official manuel du candidat for the rest.
