While cheating in exams in not unknown to us, the education minister of Bihar isn't completely wrong. Students will always risk their reputation when they're desperate. These are just some of the classics.
1. Writing the answers along the sides of the fingers
Even if invigilators do a brief check, they only focus on the palms of your hands rather than the depths of your fingers. Just don't stretch your fingers or splay them out
Stupid because: You can't keep your fingers glued together through out the entire exam.

2. Writing answers on fingers and then covering it up with rings
It's risky business considering one has to be completely discreet once the rings come off.
Stupid because: Fidgeting with rings can catch the attention of examiners.
