B.Ed

Regional Institute of Education is one of the college offering integrated programme. For details refer: http://www.riebbs.ac.in/4-years-b.sc.b.ed.php.

You need have minimum 50% for paper 2.

Yes, you can get admission for B.Ed in Indira Gandhi National Open University with 47% marks. For female, the minimum percentage is 50%. For SC/ST, 45% is required.

No, you can't, because 45% is not expectable. If you are a general category student, 50% marks is a must in B.Ed. I want to do the same.

I hope this helps

NTT does not have much value so go for the combination course NPTT, in which you may teach from pre-nursery to 5 class.
It is a 2-year programme in which 1 month usually is internship in the school the institute opted for their students.
If your performance is good, the school will give you a permanent job.
Or you may go for D.El.Ed or D.Ed course. But I think you should go for B.Ed as both NPTT and B.Ed are 2 year programmes but the value of B.Ed is more.

I think no because both courses are regular. But if you do B.A. From SOL. And regular B.Ed so there may be a chance. But in my opinion I think don't go for two course at a time it became very difficult for you to manage both the course. If any time the exam held on same date so that became problematic for you.

There are no differences between the two. Every private institute runs according to their own way like cutoff marks for admission, admission fees, etc. But they must conduct the examination under a government-registered university, so it is equivalent with government (regional or central) institutes.

Yes, you can apply for any university or college of your choice which is offering this course. Usually, there is a common entrance test conducted and you will get admission on the basis of your performance in that test.

Yes, definitely after M.Com if you want to pursue B.Ed then it will be of two years. Also B.Ed is a two year training course but some university, college and institute has integrated programme for this course. Like. Regional institute of Education, Central university of south Bihar.
