That is exactly one of the main problems people have with the current exam marking system - it simply takes too long.
For the amount of money that the exams cost, why on earth can the CAA not adopt the system that is in place in other European countries where you get your results in a matter of minutes and they can be done on a terminal???? It is an absolute scandal that the cost for exams is so high with such a poor service and the CAA simply do not give a toss.
For the amount of money spent on exams the CAA should be able to put unambiguous questions and answers in the question bank and the correct answers for that matter. There would be no need for an appeal process if the questions where properly checked before going to print instead of simply including them time and time again in an exam.
