Use of increasingly sophisticated technology to cheat in exams by students is making it difficult for police and prosecutors to crack down on the crime, said Li Zhen, member of the National People's Congress.

Li, who is also the director of Jilin Education Examination Authority, which organizes most of exams in Jilin province, including the national college entrance exam, said cheating provides unfair advantage to some students.

He said if an amendment is passed before June, it will give police the authority to take action and also provide guidelines to examination organizers.

China's college entrance examination, also called gaokao, is the most important test for majority of students. But media reports have said that in some regions cheating is common.

Chinese students have also earned a bad reputation in overseas exams.

American examination provider of the College Board, the Educational Testing Service, delayed results after allegations of cheating in Asian countries, affecting an estimated 8,000 students from Chinese mainland, in November 2014.

"It is so unfair for the rest of us," said an 18-year-old Beijing high school senior surnamed Zhang whose results were delayed.

I hope Chinese students will do much more to restore our reputation, said Zhang.
