Your school will provide predicted grades for any qualifications you are taking but haven't yet completed. It's up to your school to calculate them and usually it's based on your AS or mocks, but also factors in things like recent school tests etc.

Your FM prediction would probably be based on your Maths AS plus your teacher's view of your FM work up to the date your reference is finalised.

Note that although you can certainly send your UCAS to Oxford in October and then later add other universities, you can't change your Personal Statement or Reference. So your predicted grades will be locked in October.
