CA IPCC

If you do CA then you don't need to do MBA and if you do MBA then you don't need to go for CA. Who told you that CA has less finance curriculum? It's completely wrong. CA is totally about finance, accounts, auditing, and taxation and you can do CA after MBA but in my opinion, you should do one of these.

Yes, its good that you choose CA, but one thing you should remember that this line is full of theory paper, if you are prompt in theory part means your remember capacity, then do it. If you want to know CA processing then go to www.icai.nic.in.

Hello,
Thanks for asking.
There are various options are available for B.Com graduates.
If you want to go for further studies, then pursue M.Com or MBA.
But if you want to get a job, then you can also prepare for government job exams like SSC CGL, UPSC exams, banking exams, etc.
Government job preparation is really good option for secure job & future.
You can prepare & appear in more than one exam at the same time.

Best of luck.

For CA it is better if you have maths, as to pursue CA you have to appear for an entrance called CPT which includes the syllabus of 11th and 12th along with maths subject.
