>>11127171Well it all comes down to what 100% means. If 100% means the best in the class, then 50% means you're average. If 100% means the best ever to exist in this world, then a 50% for a student is the highest you could ever possibly expect. If 100% means what we expect a moderately good student to be capable of, then a 50% definitely means a fail.
Remember percentages are ratios, that means you need to know both parts that go into it or you'll miss the meaning of the ratio.
