Which A Level will be helpful for a geography degree?Watch this thread
What 'sort' of Geography do you want to do - Physical, Human, a more specialised subject like Geology/Earth Science or International Development?
Look at them all. Usually Unis will specify one or maybe two essential subjects, and if the 3rd subject has nothing 'preferred' or 'excluded' then PE is fine - you just need to get the grade. There is no 'secret info' about Uni admissions, nothing that only 'special people' know - what you see on the 'entry requirements' on the course page on their website IS what they mean.

As for the German you mentioned, if you want to study Geography with a Language, that would be nice. Otherwise, it's not relevant.
