> In France, most immigrants kids don't even know the possible paths to get into a top school.

What do you mean? As an immigrant to France when I was in 3rd grade [0], I knew in a couple of months that I had to go to a good high-school, to get into a good prep school, to get into a good grande école. Everybody knows this. And everybody knows how to get there: be good at math, and have good grades in general.

[0] In France, school grades are "reversed". Grades 6 to 3 are "collège" / middle school / junior high. Grades 2, 1, "terminal" are high-school.

I personally did not know about classes prépa before the last year of high school. I will forever be thankful for my maths teacher who told me about it that year, since I would have probably slacked off at university.

I know people from the suburbs who didn't even know what a prep school was until they were adults.

Blame their parents and their own lack of interest.
