If the quiz was out of 14 and I only got 3 questions wrong then why did I get a c?
Well my answer is: You don't know if every question was worth 1 mark. So if he missed 3 questions then that would be 11 out of 14 which is 78%. Then if the 3 questions that he missed were worth 5 marks all together for example 2 questions were each worth 2 marks and then the other one is just worth 1 mark then that is already 5 marks taken off. So 9 out of 14 is 64%. This is why I think he got a c on his quiz.
