Schools are urging students to appeal their results if they are of the opinion they have been awarded the incorrect grade.
Speaking out about the incredibly troubling matter, William Richardson, general secretary of the Headmasters' and Headmistresses' Conference, insisted: "If students and their teachers feel that a grade could be the result of inaccurate marking, they should ask the exams office at their school to trigger a review."
It has been suggested that evidence which indicates exam boards are 'guesstimating' a student's grade as opposed to implementing the correct marking scheme will result in thousands of successful appeals this year.
Exam regulator, Ofqual, highlighted the issue in a recent report, saying: "It appears that only after the joint meeting between OCR, Ofqual and Ucas on July 31 [2014] did OCR senior managers understand fully the significant effect that an anticipated shortfall of marked A-level papers would have on a significant percentage of students going into clearing."
The shocking approach to the marking system is believed to potentially costs thousands of students their place at chosen universities.
Commenting on the tremendous implications such an approach can have on a student's future, Liz Coatman, from the advisory service at the Good Schools Guide, said: "There have been mega mistakes in the past and this has a huge impact on the individual."
