Icai is not fair & transparent

I have given my CA Final attempt and could not clear it. Friends I matched my anwers with the suggested answers of BoS in many subjects and according to me I have got lesser marks then what I deserve. I think ICAI is not at all fair & transparent in awarding marks to students. I think most of us are suffering because of this. I don't know what improvement should I make in my studies. I worked really hard and was sure of my success. But the most unexpected think has happened to me. What do you think friends? Please share your views.
