I dont think any error in institute result.
error is only because of misunderstanding of the data given by institute.
ya this time (june 09) result %age was down to 13.85 %
1st group % was high due to very very easy paper of MAFA. I have seen many students got exemption in MAFA.
in 2 nd group % was realy down reason for that is the hard cheaking of DT and IDT papers.
this time only 46400 students of CA FINAL are appread not the 72313.
