Hello

No,You are not eligible to appear for BHU as well as JNU MCA entrance exam,because you don't have sufficient marks in your graduation.

As per BHU MCA eligibility.A candidate must have passed 12th with Mathematics as compulsory subject and they should have minimum of 50% marks in their bachelor's degree.

And as per JNU MCA eligibility.A candidate must have 10+2+3 and should have Mathematics subject in +2,and in bachelor's degree the minimum marks for the exam is 55% to appear for the exam.

I Hope This Helps

Best Of Luck!!
