CA

Hi
The highest package for a b.com hons student in delhi was 35 lakhs not because of degree merely but the interview, her analytical skills and creativity. Whether you do CA or b.com, how you learn and what you derive out of that degree will decide your salary. Hardwork can't be replaced by shortcuts so be wise and choose what you can do best, money will follow.

You are from science(math) background so N.D.A is better . C.A is also for you .but CA is mostly for commerce extreme student.
you need extra labour for selecting CA as a carrier.

you may opt CMA, CS, CFA and also may check for specialisation such as actuarial science, banking and insurance

Professional courses are never easy. If you have will to succeed and you are ready to overcome your weaknesses, work hard and can remain focused on your goal, you will be in position to do CA.
