Is it useful to do B.com correspondence for doing CA?
Yes ofcourse doing something more with a regular course is also helpful and helps in adding more to your experience and qualifications.
You can opt for CA to and make sure you have to handle both at the same time so you would need to divide your hours accordingly.
Try knowing yourself that which are the places you are good at so you can give lesser time to those topics and focus more on your weaknesses to come out with flying colours.
Anyof can work out and should not be problem.
However regular classroom program ha smore value on resume and highe r preference.
