Hello dear student,

As b.com stands for bachelors of commerce and it is a three years course and it is a graduation course. even though you belong from arts background but you are eligible to get admission into b.com after class 12th there is no problem in that . It doesn't matter if you get a very high marks or margin marks to touch the eligibility criteria but even do you belong from arts background you can definitely go for bcom

Thank you

Hello,
.
Were you a student of humanities in +2? If yes, then yes you can persue B.com in economics. B.com has no particular eligibility criteria unless you have a good score. Government collges/ private instites only consider you score in +2 for allotting admission. So just check the eligibility criteria of particular college before going for it.
If you aren't understanding the procedure just see if you have 70 to 80 % so that you will get a seat in any institute.
