AKTU - Dr. A.P.J. Abdul Kalam Technical University (UPTU)

As your graduation percentage is quite low.
So, you are not eligible for the government colleges.
It depends on the state where you live and from which state you want to do MBA.
And most important is your category. If you are OBC/SC/ST/NT/VJNT and domicile of your respective state, then you can apply for MBA with 49% in graduation in your state.
For example, if I am a domicile of Maharashtra and got 49% in graduation and fit into backward category of Maharashtra then I am eligible for MBA in Maharashtra only. I cannot do MBA from any other state in India.
And if you want to pay high amount of fees then you can go for management or NRI quota.
There are some colleges which are allowing this. But remember they are not reputed.
So, think twice before you invest.

There are many aspects of comparison:
Fees:- Being a government college it's obvious REC Sonbhadra has less fees than the both other private colleges. Locality:- Locality of REC is very poor in comparison to bbdnitm and srcem but it's full of natural beauty situated at hills during rainy season weather became so pleasant now it's upto you. Placement:- Rec Sonbhadra has a great achievement in off campus placement in last year you can check on website, atmosphere of coding and placement is touching the peak. No doubt off campus placement can be taken from other two colleges also. Academic:- There is lack of Holds (government professor) in REC so assistant professors aren't much skilled still they worked hard, private colleges like bbdnitm and other has skilled and good teachers also classes run timely because it's their priority and skilled students provide fake to college.
