Under the negative marking if you answered 4 wrong you have a maximum of 46%. The maximum number you can get wrong and guarantee a pass is 2, if you get 3 you HAVE to get the other 7 correct to scrape in with 60%, although if you have answered 7 correctly then you have a pass regardless of how many you subsequently get wrong.
So the negative marking at 60% did give a few more chances of passing than a straight pass mark of 80%.
I think the previous poster was getting slightly confused - answering 6 correct and leaving 4 blank would give you your 60%.
IMHO there might be problems with the questions, multiple choice questions are the hardest to write correctly but conversely the easiest to mark. There is a slight problem with
what is being asked (we are not testing higher levels of learning objective, look up Bloom's Taxonomy on Google if you are really interested!). There is also a misconception that all multiple choice exams should be similar to the old CCS.
Look at it this way:
1. The alphabet has 26 letters, what comes after A?
a) B
b) C
c) 7
d) Goldfish
Now by the power of deduction you can reduce this to 2 possible answers meaning that the guessers amongst you now have a 50% chance of getting it right instead of 25%. To write MCQs correctly your distractors must be plausible answers.
Negative marking was supposed to stop people guessing but I think it has not, leading to the removal of the system and the introduction of the 80% pass mark. I think we doth complain too much and now it biteth us on the arse!
