PCC 2 Groups

The Thing is that when u write both groups together, the chances of u passing the exam is a bit brighter in the sense that even if u score only pass marks in one group and good marks in another, u can pass the exam if ur total reaches 300 and above...suppose u score 140 in group1(getting >=40 in each subject in tht grp) and u get 160 in group 2 in one sitting, ur aggregate in both gros in that stiing comes to 50% and u have passed individually in each subject. So, the deficit in 50% in grp 1 is offset by grp2 if u write in a single setting but if u appear grp wise, the benefit of setting the deficit in1 grp with surplus in other is not allowed
