The teachers are kind and always ready to answer any question if you don’t understand something. The presence of more math-oriented courses would be a plus. I guess the administration could improve the way they distribute the semester lectures, because I think it’s a bit extreme if a student has courses from 8 AM till 7 PM without pause, except for the lunch break of an hour). I’d recommend that the university has more English courses. Also, the university provides meals for 1 euro if you receive financial aid or 3.30 euro if you’re a simple student. Also, it has like a Cafe where students can buy a sandwich with a fruit and yogurt for the same tariff as in the restaurant.
In general, I’d recommend the university for your studies, but only if you’re at least somewhat confident in your French.
