No, I don't think so. One of the most important elements of a public exam is that it is fair. Allowing students to bring mobile phones into exam halls will only cause trouble.
Some candidates may use the phone to secretly send answers to their friends. The receiver can then take a toilet break to check the message.
Students who have a mobile phone may also get vital information from the Web.
Those without a phone are less likely to cheat.
Although mobile phones are supposed to be switched off in exam halls, many students have complained about ringing handsets. This is unfair because the noise may disturb students. If this affects students' concentration and they get less marks, will they be compensated?
