Negative marks for wrong answers in entrance exams - is it fair?Over the years I have been submitting many articles related to admissions and online entrance exams. I have always wondered as to why marks are deducted for a wrong answer. In most cases it is 0.25, in some, like KMAT, it will be a full one mark. I do not recall having marks deducted for a school test or exam (though I can't remember if in college this was the system).
Just think about it: an answer can be right or wrong. So if the right answer gets one mark, the wrong answer should simply be given a zero. Why minus? Also, are the deductions always more for professional courses like MBA? Whatever the case may be, is it really fair? Deductions can badly affect the overall score of the student while a zero may not. What's your take on this?
