Hello Sachin,

See class 12th marksheet does not includes your category so it does not matter what category you have chosen for your class 12th but what matters is what category you will be choosing while filling application form for DU, as you have mentioned that you want to apply for DU Admissions under SC category so if you have valid SC category certificate then you can enroll yourself under SC category for DU Admissions. There is no need to change your category if you have chosen another category in class 12th because the category which you have chosen in class 12th for board examinations will not be considered for DU Admissions.

For admission to DU you need to fulfill at least the basis eligibility criteria which is common for all UG programmes :-

You need to pass your class 12th from recognized central/state board and the minimum qualifying percentage is different for different courses as per their subjects, so you can check detailed criteria of UG programmes from the link given below :-

For admission to UG Programmes offered by DU your "Best of Four" percentage will be taken for preparing merit list which means that from the total subjects for which you have appeared in class 12th, only four subjects in which you have scored maximum marks will be considered for your merit selection. For complete details kindly check out the link given below :-

I hope this information helps you.

Good Luck!!
