hi,
see if you have taken science stream, it is mandatory to take physics, chemistry and mathematics and in fourth subject you can take biology/ statistics / computer science etc.
if your school do not offer computer science then you need to take another subjects from the given options, however you can learn computer science by taking private coaching if you are really eager to learn it.
