dear student,

Pretty much hardwork required.For commerce course from good college in DU(assuming you a commerce student as DU is best for that), you require at least 95% in boards. This is based on this year's cut off and you should keep in mind that each year cut offs rise by 0.5–1%. So gear up if you desperately want to get in DU.Also, if you are in CBSE then you need some luck from the examiners ( which I didn't get and my du dream got into vain).So all the best!!!

hope it helps...if yes...please upvote
