Hello Jayesh, 

BATU has their own way of evaluation of the exams. They have a mid semester,  end semester and remedial exams. In the final evaluation,  they consider 20% of mid semester theory, 60% of the theory marks of end semester and 40% of practical marks. They will consider 20% theory and 60% practical marks in case of the continuous mode. Other details regarding exam pattern and their exams in general are available here :  https://www.batupapers.com/2018/09/examination-pattern-of-dbatu.html?m=1

Hope this helps :)
