A-Level grades with Swiss Maturité

Hi everyone,

I'm currently doing my first year at the college, preparing for my "Maturité" that I'm going to have at the end of the third year. During the third year, there are, unlike the classical A-level in UK, fourteen subject: mathematics, italian, english, french, biology, chemistry, physics, history, geography, art, philosophy, "travail de maturité" (a sort of thesis of about 20-30 pages about a subject, which counts as a grade), the "option complémentaire" which is choosen in a wide range of options such as history of the religions, computer sciences, sport, ... and, finally, my specialization, ancient Greek. At the end of the third year, all this subjects have a grade, and 5 of them (ancient greek, english, french, italian and maths) are subject to an examination which is the "Maturité" (the grade at the "Maturité" will be combined with the grade of the year to make the final grade). Now my question is: if I whish to do, by exeample, natural sciences at Cambridge, it is specified: "Essential At least two science/mathematics A Levels/IB Higher Levels", I do have at least to science/maths subects (bio/chemistry/physics/further mathematics) but only one of this four will have a grade at the "Maturité". Cambridge wants at least two of this subject at my A-level, which is the case, or Cambridge wants at least two of them with the grade at the "Maturité" ?

Thanks for reading my long text (which contains certainly mistakes, and I'm sorry for that), and thanks for your future answers !
