Just found this.
To be eligible for student Sécu you have to take 20 hours of class a week. That is a TON of class time.
I have that answer, at least.
Aaaannnddd, Alliance Française has a Medical French class that would fill 9 hours a week. For those who may think (ie my dad) that this would be a ridiculous way to waste a year when I should be pursuing my medical studies.
