École Normale Supérieure's students' class rankings and ranking on the national concours exam for agregation? Are the École Normale Supérieure's academic records publicly available anywhere?

Specifically, I would like to know what class rankings were historically there, as well as its students' rankings on the national concours exam for agrégation.

thanks
I found half the answer:

Here's the link to records for rankings in the concours exams for aggrégation:
