One may ask how do I toss in the examination hall. I do it with my pen or pencil. I rotate the pen/pencil and watch where it stops. If the pen nib or pencil lead head stops to my right, it is the right, and the left is wrong. In other areas, I take out a coin and toss for the head to tell me to go ahead.
