Exemption in papers

hi.........  U need 2 b present in all the subjects in that group........

yes you have to be present at all the papers

Does my performance in the subject in which am not prepared affect my score in the subject  in which I want exemption ??

no it does not effect

No, it will not affect your score in the subject  in which u want exemption. It is Jst a formality.
 

Good Thinking..... bt it can not work..........

If one have already exemption in one of the paper of group whether he can get exemption in his 2nd attempt in other paper
