This reminds me of a story a friend who is a teacher recently told me: One of his students was so nervous during an oral exam that he could barely form a complete sentence. So the friend of mine, in consultation with the exam board, gave the poor guy a second chance on the same day - that didn't go particularly well either, but was enough to pass. The parents of the nervous student sued because this procedure did not comply with the examination regulations. They won and managed to get the exam repeated a third time - the examination board stayed unchanged. You can perhaps imagine how this went for the student, who was understandably all the more nervous the third time around. In the end, he didn't graduate, not because the examiners were vindictive, but because they had to grade the student purely based on his performance which wasn't good enough because the poor guy couldn't get a coherent sentence together again. If his parents hadn't sued, he would have graduated.
