Final- single or both group?

Since u are saying that u hv prepared well 4 both grps, u shld definitely give both groups. The decision regd both grp/single grp shld be taken solely based on ur level of preparation. Dont bother too much about the passing policy of ICAI. I have seen people who hv failed while the pass % was 20 and the same ones cleared when it plumetted to 3 %. Also there is the set-off facility which we get on attempting both grps. Hv seen marksheets of many guys who hv cleared even though marks of their one grp fell short of 200.
