Having read Miki's posting, I'd just add that the whole coefficient thing changes according to which baccalaureat you do. Obviously if you are doing S(cientifique)then science and maths count for a whole lot more than if you do L. If you do L(itteraire), I think I am right in saying that maths is done in premiere as an epreuve anticipee like French. Miki's coefficent look to me like they are for ES, because the economics seems to feature. If university is envisaged, there are three bacs worth having, S - scientific, ES -economic, and L - literature (although snobby French parents might try to tell you that the only one worth having is S). These are all done in the standard lycee, along with STT, which is a tertiary bac which is not well seen. Otherwise there are professional bac, some of which are wonderful, some of which aren't. It is incredilbly different to the English system and takes some getting used to!
