i called the Bayrische Bildungs Ministerium...
every A2 grade gets converted as follows:
A----1,0
B----1,75
C----2,5
D----3,25
E----4,0
i know its a joke...they justiefied it by saying that A being the highest mark should be 1,0...and E being the lowest mark still worth a pass is equal to 4,0....they do not take into consideration that u only need like 40% to get an E..whereas u often need 50-60% to get 3,5-4,0....its ridiculous....and obviously they dont care that at A-Level u just do 4 subects..
