Note: ENA does not happen on the same level as the others. All of the above but ENA are post bac (post prepa of course) entry exams. ENA exam is after you’ve done a grande école like Ulm or SPo. This might affect the qualitative results of the survey not displayed here in the quantitative as it narrows the pool of candidates and their backgrounds. The data might be correct but this specific École does not deal with the same level playing field as the others, as they are modes of preparing for this one. Comprends qui peut. (Note: it is a system I know well but do not defend or condone, as I left it precisely for the reasons shown in that study, but precision is key)
