Doubts regarding 60% exemption

Hello

           I gave my CS Executive module 2 exam for the first time in December 2014 and I got 78 marks in Industrial Labour and General law and I got 40 marks in Company accounts and 31 marks in Capital market. So I got exemption in ILGL. Again I gave my second attempt in June 2015 , from that exams I got 40 marks in company accounts and 46 marks in capital market. I failed because there is no aggregate. Iam going to write those two papers again in December  2015. My question is ,  will my  exemption stays for the December 2015 exams or Should I write that ILGL paper again in December 2015.
