BSC agricultural ranking is calculated based on the marks you aggregated in the following manner:
     
          Consider an example of-

• If you secured 183 marks in Mathematics.

• If you secured 169 marks in Physics.

• If you secured 175 marks in Chemistry.

• If you secured 189 marks in Biology.

Then the cut-off marks will be -

    Cut-off= (183/4) + (169/4) + (175/4) + (189/4) = 179
   
179 wil be your total marks. Then based on your marks your rank will be predicted on the basis of which Category you belong to.
