Hello Krishna,

The admission in B. A. course is done on the basis of class 12th marks. 

The eligibility for this course is as follows -

1) A minimum aggregate of 50% is mandatory in 10 + 2 level.

2) All SC/ST candidates have a relaxation of 5% in the minimum aggregate.

Since you belong from the unreserved category so you might not be able to get your desired college or desired stream for the B. A. course but you are definitely eligible for this course.

Hope this helps.

Good luck!
