The test results of four students were canceled as they were assumed to have spread rumors on micro blogs declaring disorder in the exam room in South China's Guangdong province, China Youth Daily reported on Saturday.

The four students recently attended an English speaking and listening test, an advance part of the national college entrance examination in Guangdong. They claimed on their micro blogs after finishing the test that the exam room where they took the test was disorderly, undisciplined and invigilators even handed answers over to some students.

After learning the information, The Education Examination Authority of Guangdong province launched an investigation and concluded that what the students alleged was fabricated. "The four students wanted to vent their discontent via the Internet because they did not get good results," said an official from the authority.

The authority defended the decision to cancel the four students' test results by claiming that they disturbed the examination given that the exam was still going on when they published the so-called rumors on micro blogs, and their posts also defamed the invigilators.

However, some netizens and education experts thought that canceling the test results was an over-severe punishment.
