With more universities and offices requiring English qualifications from graduates, students are turning to hiring other people to sit their English exams. The police in HCM City's Thu Duc District are investigating a case in which 34 students at the HCM City University of Agriculture and Forestry hired impersonators for their English exams. Last year, 10 impersonators were uncovered. Meanwhile, universities which require students take TOEFL, TOEIC or IELTS tests as English graduation exams have received a number of fake certificates.
