I failed in class 12th (science). I want to pursue B.Com now. What steps should I take for admission?

I’m sorry to hear that. You can pursue B.Com after failing in class 12th science. The eligibility criteria for admission varies depending on the college or university you are applying to. Some colleges require a minimum of 50% marks in class 12th while others require a minimum of 60% marks in class

Hey, for taking admission in Bachelor of commerce you need to pass out 10+2 standard examination with a minimum of 60% marks in commerce stream. But as you have failed in it now you need to drop 1 year, clear your backlog and then you can take admission in graduation of commerce.
