After the months in such a highly competitive environment, I've seen and heard of a myriad of cheating tactics, amongst which are:
Peeking over your neighbours' shoulders; sneaking sideway glances at test scripts held too high; an unoriginal idea that is nonetheless, probably the safest.
Approaching friends who have taken the test for help. Inclusive of: asking for hints subtly; asking for hints not-too-subtly; and asking directly for the questions.
A secret code that consists of a wayward eraser, muffled coughs and the tap-tap-tapping of a pencil.
The One That Tests Your Friendship
Similar to the Cooperative (see above). Slight difference lies in the fact that your friend is liable to get into a lot more trouble with this one. An example of this type: actual passing of test paper over to friend, while invigilator skulks around the other end of room.
Makes me wonder sometimes: why should I place so much importance on being honest and struggle my way through school, when around me I see people taking the easy route out?
