the daughter of a person known to me is appearing in this years cbse board exam for class 12 in the science stream in march 2014. she has maths as an additional subject. now if maths is there in the examination admit card as an additional subject along with the main subjects 2 languages, phys, chem, and bio. she wants to know whether she can skip appearing in maths exam and still pass, assuming that she passes the 2 languages and phys chem and bio. again mathematics is an additional subject can she is totally unprepared thus she wants to skip appearing in the subject. is it possible to do so and pass if she manages to pass all the other subjects.
