ASUKA:“It's ridiculous. Who cares about grades?
I've got absolutely no interest in
the old-fashioned grading system.”
Zusuchan: Pretty sure the Germans also have a graded school system (grades range from one to six, IIRC), so unless in the Eva universe things somewhat changed thanks to Second Impact or Asuka had a special childhood, the "old-fashioned grading system" comment doesn't make much sense and neither does Misato's following "do as the Romans do".
