Can you give your opinion please??

I took SAP terp-10 certification exam before Christmas. I got mark 50. The passing mark is 51.

During the exam I noticed one of the question is wrong. I informed the SAP invigilator present at the exam. He advised me to carry on the exam. At the end of the exam I wrote on piece of paper which question was wrong and the reason for it.

Recently I had communication from the SAP as follow:

u201CQuestion 29 was looked at by the SME and they have stated that this question is correct and therefore there are no grounds for a re-mark.u201D

I am confident that the question was wrong. And if they give me the mark for this question I will pass my certification.

Now; What would you do if you were in the same situation??
