What you need: Bluetooth-enabled watch; Citizen i:VIRT M, $350; Sony Ericsson LiveView, $78; Pebble Watch, $115

Risk level: Low

Admittedly, checking your mobile phone during an exam is very tricky business. Checking your watch, on the other hand, is not. Though pricey, a Bluetooth-enabled watch is one of your best bets for receiving text messages from your friends while taking your exam. Citizen Japan’s latest Bluetooth watch lets you check e-mail and text messages directly from the watch. Sony Ericsson’s LiveView does the same at a cheaper price, but looks like an iPod Nano attached to a wristband. Warning: You may get hemmed up for rolling into class with what looks like an MP3 player on your wrist.
