BEIJING, Oct. 14 (Xinhuanet) -- Beijing municipal education department will distribute cell phone signal detectors to college entrance exam supervisors in an effort to prevent the rampant cheating via text message.

Anyone found cheating, is forbidden from taking the test again, accordingto Li Hongjiang, an official taking charge in college exam under Beijing Municipal Education Department.
