thnx a lot sir..for ur valuable suggessions..but let me told u dat i m too suffering frm d same situation..but in ma mind der's sumthing different going on...m thinking dat if some1 is nt able to score good marks in 1 sub of any group..lyk e.g.costing is very hard to score in pcc..2nd group..if i go for 1 group each i'll nevr b able to pass d exam without compesation of marks..so as i knw dat's going to happen wid me..i'll go for both groups, which can help to pass d whole pcc ....just by securing 40 mks in costing and scoring high in othr subjects....i just state dis coz i guess you shud knw wat 's the thinking of suffering one.......
