Dear Yash....,
I think you are going to join Articleship Training now.... So If you want to do M.B.A. Finance, it is possible only by way of Distance Education Mode...Its Good that If u join M.B.A. (Distance Mode) alongwith CA... it will help u in improving ur writing skills in the examinations... also, keeping the marks of ur Distance mba, u can evaluate yourself for ur progress in CA..
Well as far as the worth of doing a distance mba is concerned, it will surely add a value to your resume, BUT the value added by it would be much less than doing a regular MBA in the top B-Schools.. if u have the capacity and patience to study further after CA, do join MBA in some reputed B-School like IIM, etc.. there are a lot of executive programmes offered by them... The value added by the B-School MBA will be MANY TIMES HIGHER than distance Mba..
CS is better than MBA Finance in Distance Mode.................
Best of luck for ur endeavours..................
