Education in France, early 1800's

I've searched history french eduction, history french universities, french universities 1800's, french education 1800's, napoleon education, napoleonic education, romantic era education, romantic era universities, and so on and I haven't been able to find a comprehensive breakdown of what I'm looking for. The only lists I can find are for modern educational structure and I know that prior to 1880, the educational system in France was significantly different.

What I need is a list of the education levels for students in France, from 1810-1830, including all secondary and post-secondary levels, the age at which a student would be studying at that level, and what they would be studying.

I know from some extensive research on bohemian life that in London at the time, the dandies were very much "career students", as the higher classes could afford education for the sake of education and it was sort of a pastime for them, but I don't know anything at all about French history (the extent of my French history knowledge is Rousseau and some Napoleonic warfare).

But the point at the end of all of this is whether or not it would be realistic for someone in their mid-20's to still be considered a student and if so, how?
