Technology has certainly made cheating on school work easier. Once upon a time, students had to write answers on their hands; now, they can input answers on their cellphones, or in dictionaries used to hide a cellphone.
Another option, of course, is to just hire someone to take the test for you, like the 70 students caught in Shanghai using substitutes to write their CET English exams.
Current regulations regarding the use of fake identification prevent any of the substitutes from being penalized. Instead, the students that hired their stand-ins could face a one-to-three year ban on taking the test. They may also be identified to their employers with a “recommended punishment”.
