Whether IGNOU B.Com Degree(Open University) is accepted for MBA Admission to NIT's in India?
No, No NIT in India accepts an degree from open University for MBA.
Most of the NITs have an eligibility criteria that the candidate must have scored atleast 60% or 6.5 in his/her graduation and must have a degree from a full time University along with necessary scores in CAT examination.
Hence, you're not eligible to apply.
Best of luck
