Hi, Among these two, Patna University is better for studying BBA. But if you are looking for a very good placement right after BBA. You may find it difficult because the university isn't able to provide good placements to students except for a few colleges like Patna Women's College. You can apply for these colleges in Patna apart from Patna University and Vanijy Mahavidyalaya :-
1. LN Mishra Institute Of Economic Development.
2. Amity University, Patna campus.
3. St. Xavairs College, Patna.
4. BIT, Patna.
5. Indian Institute of Business Management, Patna.

No, only computer is compulsory.

Yes, maths is compulsory.
BCA eligibility: PCM at inter/+2 level.

Hi there. Well life at CNLU Patna can't be compared with Amity or Alliance at all. However it's not the best NLU but surely better than Amity or Alliance. Also you have an NLU tag which makes you stand indifferent among others. Internships can be managed on your own based on your CV. Also placements would depend on your marks again.

Hi Shikha!
Although the college has a placement cell, it is not that great. But the reputation of this college is good so sometimes this college certificate works well and proves to be beneficial to get a job in the market.

The chances of getting into N. College, Patna University - B.Sc.(Hons.) in Mathematics with the general category are very less.
