How to pass CA inter (old scheme)?

Iam also.first try to clear gr1 only

Yes if you clear group 1 with old scheme in 2020 may.. then you have to write only group 2 with revised new scheme from 2020 nov onwards..and also if you are not passed any group of ipcc under old scheme but you have got any EXEMPTION in that, those are tranfered to new scheme of exam,then remaining subjects only you write....

My personal suggestion to you.....
If you are not clear both groups ,so you have to MORE concentrate on COSTING&FM in group1.. because once you are getting EXEMPTION in COSTINGFM then you will get TWO subjects as EXEMPTION in NEW SCHEME...
ALL THE BEST.....

Thanks a lot.
