TITLE: Studying mathematics abroad - specifically France
QUESTION [24 upvotes]: I have tried to avoid asking a "soft question" on here because I'm not sure if they are appreciated or not.  However, this is one that has been bothering me.  I was recently talking to a few friends of mine about my desire to study in France.  I have a B.S. in Math, and am working towards a Master's degree.
We poked our noses around and posted various threads on different websites.  So far we have gotten a lot of advice such as "Don't waste your time."  Or other things such as "French universities have terrible math programs."  However, constructive advice has eluded our questions.  We are just generally met with antagonism towards the idea of studying in France.
My question is specifically this: what is a reasonable French university at which I can study mathematics.  I would like to study in France.  I have a reasonably strong command of the language.  However, I may be hamstrung by the fact that I had only had ok/good grades in my math courses.  Lot's of B's and B+'s.  Anyway, I'm not looking for the oppurtunity to study at the grande ecoles.  At the same time, I would not want to go to their equivalent  of some sort of third-rate state university.  I'm just interested in trying to seek out an oppurtunity to be abroad while studying mathematics.

REPLY [4 votes]: French system is unique regarding other countries in that fact that it is generally considered as a shame and a disgrace for a student to enter at 1st year of French public universities. This means that this student has failed to all the 'Grandes Ecoles' entry tests (Big Schools) but also to all the less prestigious engineering schools and the technology institutes - which are really like a thousands - 
The paradox is that the teachers in these public universities come often themselves from the Elite Grandes Ecoles.
The other paradox is that a great deal of very good mathematician and scientists comes from public University despite this bad reputation.
For example Grothendieck did not come from the Ecole Normale Superieure but directly from the university of Montpellier.
At Phd level , students from Grandes Ecoles often enter directly public University.
Note that the mathematics taught at Msc level in Parisian Universities are often themselves quite good.
The French system is based on a sort of cruel and hard elitism which ages from Napoleon !st and most of the Grandes Ecoles do not provide Mathematicians but Engineers. Almost all Elite French Mathematicians come from one only ultra-selective school which is the Ecole Normale Superieure of Ulm.
This system seems a bit outdated by now and frankly a bit stupid ( I am from one of the top Grandes Ecoles myself )
With regards to the U.S system, the U.S system is for me unable to produce mathematicians on their ground, they need to constantly import them either from India, China, Russia or even France.
I wish we all could be like Grothendieck!
