ca with regular college

I think although CA alone is enough, but still its always preferable to get a regular b.com degree instead of a correspondence.  If you can carry on with low attendance then u should definitely continue your regular b.com, you may have to put some extra hard work to carry on both of them but once you make it, you will gain from it.  Have a talk with your teachers to help you in attendance matters.  Also keep in consideration the requirements of 112.

Best of Luck
