Which is exemption oriented paper in gr 2 final?

dear frens, I have been ruined by CA since long due to second group pending. I expect genuine suggestions from you frens who can very constructively guide me with your experience. I m suffering every time due to lack of aggregate by few marks like 10-15 which is as a result of not having 60 plus marks in any paper. I get too much frustrated and sometimes plans to quit CA but where can I go at this stage leaving CA. u all are aware that without having 60 plus marks in either paper in any group, its almost impossible to clear the group but as regards second gr papers, I find no paper worthy to secure exemption marks . pls kindly suggest me , which paper should I target for exemption and what would be the best possible mode of preparation? thanks .
