Question

Hi,

 

for example: 

In X board if you fail in 1 subject, the final result will  show as fail only. Even if you score above 90. 

 

I want a logic for code which should show as fail in the result section even if 1 subject score is less than 35 .

 

In my code it is showing as first class  even if I put 34 in one of the subject.

 

Please let me know what logic should be applied.

 

Thanks,
Anurag
