Signal Tapping
Unlike calculators or communication devices, this is a fairly low-tech method of cheating. You find a friend, or group of friends, and come up with signaling methods. Works well for multiple choice exams. Something like, cough is A, sneeze is B, stomp is C, clap is D...etc. Or you can use pencil taps, scratching or yawning, whatever. Just make sure everyone understand what is what so you all don't get confused and fuck up. Oh, and also be sure to have the same form of the test! This method, when executed properly, works very well, and is near impossible to prove. Even if a teacher suspects you are cheating, they are likely to have little evidence of it!
Advantages:
- No physical evidence
- Useful on multiple choice exams
Disadvantages:
- Peers can be confused and give/get wrong signals
- Overdoing signals can become suspicious
- Needs some practice so everyone is on the same page
- Not useful for essay exams
