Consider a script originally awarded grade C but reduced to D on appeal. The second examiner's subjective judgment does not automatically negate the first examiner's view. Indeed, a third marker may re-award the original result. This is a consequence of the unreliability of scoring - a factor that cannot be entirely eliminated in any assessment system.
So, students who feel their grades are too low should appeal. If an appeal results in a lower grade, they should appeal again, this time using the evidence of the original grade, awarded by the examining authority, in support.
