U can pursue M.Com or prepare for MBA or there is a good option to prepare for govt. exams for the post in IAS , IES , IFS etc. where u can get good salary and government perks by clearing just different levels
the graduation marks won't affect your salary or marks in entrance

It would be challenging to get admission into any good college witj below 60% in 12th so either look for private colleges or score very high in JEE.
If you are not sure of becoming an engineer, I would suggest you to take a career aptitude test as it will help you in understanding the further path better.
All the best

If you want to be an economist or civil servant then BA (Hons.) economics is a good option. If you want to do Commerce & Accounting/MBA in future then B.Com (Hons.) will be a better option.
