IIBF — caiib bfm exam

One question in the exam had options in which two options were correct. I would like to revaluate both questions and answers by iibf faculties. And also only 21 questions were only asked from macmillan textbook rest questions were so vast that a person working in bank cannot able to study after their working hours but need thorough coaching that is not possible for working people. What iibf wants to prove that they conduct the toughest exam and gaining money from students who aspire for promotion again by applying for exam. The students who had passed two years before wrote exam that is so easy and now the same book is being taught but questions are tough. So there is no equality in the exam
If tough paper is given they should reduce the cut off too like ibps exam model. Or else some grace marks should be given to students who can take aggregate in all three together with 150 and because of one subject they have to study again the whole portion that is so vast and time consuming for working people.
