Hi,
Yes, you will get admission in IEM. But, you must have passed all the subjects of class 12th. They will verify your marks at the time of admission. Also, this college is famous for its placement, so after your graduation, you can expect a good job in top IT companies.
Best of luck.

Hello Aryan,
I am afraid your unique solution to do 12th again will not be able to work. This is so since it's the "first" passing year of 12th that counts. I feel you have lost the opportunity to seek admission in NIT etc. By choosing medical. However you can think of seeking admission in private colleges or deemed to be universities where this constraint does not apply.
Best wishes.

No, it is nothing like that. Apply on DU website. You are eligible, if you match the cutoff, you will be admitted.

Yes, My friend had submitted and it's been approved.

Government colleges have admission on merit based on 12th board marks and that changes every year. It is different for different states every year. You should go through the previous trends of cutoff for the required course. Also, check if you've any reservation.

Yes, the college accepts students from NIOS board too as it is a recognized board.

Yes, you certainly can. NIOS and regular 10+2 hold the same value for UG admissions.
