Just a quick point to add to Oxford Blue and Alex's already excellent replies:
You seem to be getting obsessed with "modules". The CAA don't know or care about modules, a module is something the schools have invented to make our lives easier. As far as the CAA are concerned, you can sit the exams in whatever order you want. )(Almost) every school put different subjects into different modules depending on how they structure their course, and one school actually has more modules than the others, I believe - they obviously think that this suits some students.
