Hi,
With 67.6% in Class 12 and over 45% in each subject, and belonging to the OBC category, you meet the minimum eligibility for many undergraduate programs, especially in arts, commerce, and some science courses. However, admission depends on the cutoffs of the college you're applying to. If you're aiming for DU, keep checking their Common Seat Allocation System (CSAS) portal for updates.
Hope this helps!
