Ipcc exemption rules

Hi. i cleared my cpt in dec 2009 and gave nov 2010 ipcc attempt both groups. but didnt cleared it. I'm planning to give it again in November 2011 attempt. if i get an exemption in any 1subject in any one group. and doesnt clear IPCC. so what are the rules or criteria for appearing in the next attempt. Do i have to appear in all exams again or just the ones i dint get exemption in. n what about the marksheet. does it show in the next attempt that such subjects are carried forward due to exemption or just marks of the present attempt.

Please reply in detail everything.
