A recent online survey conducted by McAfee has found that about 62% of teenagers in the US say they have seen or heard of another student using technology to cheat in school. The firm surveyed about 3,902 high-school students in the US, Australia, Canada and the UK. Students say it is easy to take a cell phone photo of notes or test answers, then peek at it surreptitiously while taking a test. Many respondents did note, however, that vigilant teachers will be on the lookout for those wayward glances.
