Maths Spl

I would let you know that if you have cleared the overall cut-off then it is not compulsory to clear a particular subject's cut-off.

It depends on which course you are willing to take admission. For most of the course, having maths till 12th is not a compulsion but for courses like B.Com (Hons) or BA (Hons) economics maths is a necessary.

IIT-Bhubaneshwar is far better among the three. Many people want to get admission there and it is a highly reputed college.

Go for colleges in Mumbai University or colleges of South Campus in Delhi University.

Real Analysis by Bartle and Sherbert.
This is a good book.

Yes, you may not count maths in best four subjects.

None of the private colleges has less expenditure. If you're thinking of going to a private college, then you must be ready to pay around 80k-1.5 lakh for academics ( excluding other living charges).
If you are from ST category, then you might have some chance of getting admission in University of Delhi.
Hope this helps! :)
