So (for good reasons) DS2 wasn't able to go on the school trip to Berlin in year 12. He tells me that both his German A level teachers and his German tutor have said that he really should ensure he goes to Berlin in year 13 in order to do (very) well in his oral exam - apparently they tell him that students with first hand experience of the city (and the various sights the school went to) do better. For context, DS is aiming for an A* and hoping to go to Cambridge. He has also spent a month in Germany (not Berlin) this summer.
Are there any German teachers around who can tell me if this seems right? Does a few days in Berlin make a (big) difference?
