AAC/ABC/BBC. I would say Economics will be a predicted C as you weren't far off and due to some repeated content in the A2, it could be said to be easier to pick up marks in an Economics resit than in some other subjects.
German you may be predicted an A as you're applying for it so the teacher may think it will help your application to be predicted an A, or be confident that you have the passion to put in the work required to improve it.
AAC possibly - some schools tend to predict +1 on AS grades, I guess it depends on their experience of improvements between AS and A2.
