i had completed 12th commerce with 47% so which is the best field for me to make my future bright

you can do BBA and then MBA

u can do ca and cs also.

you can do B.Com or BBA or Hotel management then try for MBA. these are the some best suited course for you. where as CA is also one of the best option for commerce students but with 47 % i dont think you can able to cop up with CA. so better try for BBA or B.Com
