ahh it makes you feel good doesnt it that we pay so much for the exam fee, only to have a computer mark it and no one question or double check the strange results that the computers throw out
It could have been for a number of reasons, people have put the wrong exam number on the answer paper, invigilators put the wrong exam number on paper (then everyone would be getting 0), did you skip a question and then not put the answers in correct boxes?
Even then sounds like a computer
as even guessing you would get some of the answers right.
Good luck, I am sure it is just another balls up at the belgrano
