You've probably considered it, you may have even given it a whirl just to see if it'd fly; using technology to your advantage in testing situations is most often regarding as cheating, as was the case when proctors recently busted a ring of Vietnamese test-takers attempting to cheat on their college entrance exams. More than 20 hopeful students paid between $1,250 to $3,125USD to get wired up with wigs and shirts that would allow them to communicate questions and answers via mobile phones without being discovered. The potential gain was apparently worth the risk, especially since only 10 percent of applicants in Vietnam get accepted to universities. Once again we see that crime doesn't pay, but we can't help but give props to the high-tech hijinks.
