If you think your school is overly cautious when it makes you ditch your phone before a big test, you haven't seen anything yet. BuzzFeed News has learned that multiple universities have issued blanket bans on all watches during exams in case students are wearing smartwatches they could use to cheat. According to London's City University, it "wouldn't be practical" to have proctors checking every watch to make sure it's analog -- it's easier to make you write with bare arms. The move is unfortunate if you're used to glancing at your watch to gauge your progress, but it does make sense given how easy it is to get memos, text messages and other unfair advantages on your wrist. Whether or not you think smartwatch cheating represents a major problem, it's probably a good idea to leave that Pebble or ZenWatch at home during your mid-terms.
