What after CA??

CS IS GOOD OPTION WITH CA                                

Focus more on gaining practical exposure, increase you application based knowledge and try to master the subject. This will be the backbone for your professional success and development in the future.

I have just concluded my GMCS, same quests. were raised there & i am giving the reply of faculty members,

Acc. to them after CA u should choose the field of your interest and should focus on specialisation in that field...ICAI is running many post qualification courses like in IFRS, Valuation, International Taxation, Financial Management etc.  Similarly for audit related field CISA/DISA etc.are there...

So do think about this aspect too...

Otherwise cs is also good option & regarding MBA, if u do it regular (if age permits) then it may give u some value addition...distance would just be an addition of degree....(i dont have much detail about cfa)
