Grading on a curve means that you are ranked and graded in terms of how you do related to the rest of the class. Only the best people in the class get As. The next few get Bs, the majority get Cs, and so on.

It becomes unfair when you have a class of people who are all good students, because only the top few will get the As.

Think of it this way:

If the test taken has 100 questions. Normally the perfect score is 100% meaning 100 correct answers.

On the curve, the perfect score is based on result. So if the best test score was 90 correct answers, then the new perfect score is 90, not 100.

So where as typically someone with 60 correct answers would have gotten a 60 out of 100, now they get a 60 out of 90 with grading on the curve.

Hope this helps!!

people with a’s still get a’s however their grade doesn’t get bump up like a person w/ a D. a D person could bump up to a 78% with a curve. A person with a 95% mite only go to a 98%
