The New Age Scheharazade has a whole set of sizzling ideas (and a very well-thought Plan B as well) for board exams:

[...] Wherever you find a suitable question, insert a line about how exam stress is killing today’s children, and how a recent study has proved that they’re losing hair at an alarming rate. Then tear out a clump of yours and strew it about on the page. Fold it in carefully.

Oh and she has a keen observation as well:

[...] Grab hold of the nearest engineering student, and make them give up all their cheat codes and tricks. (I’m telling you, these guys are the goods.) Also threaten the best student in class until she agrees to be your cheat partner.

Like she says, it is all about planning ahead! :)
