CA n CS ---possible???

I think you are pursuing B.Com also.  Only one course is permitted with CA.  You need not to file 112 untill your articleship starts (which will start only after passing first group of IPCC) so go ahead with cs foundation.  But officially you can pursue only one additional course during articleship i.e. b.com/CS.  So take care for this

 thanks...but what is the 112 dat you talked about?

If you want to pursue any additional course alongwith CA during articleship period, you have to take permission of ICAI.  This permission is obtained through Form No. 112.  Your CA under whom you will go for articleship will also have to sign it.  Here follow this link and have a look at Form No. 112
