Admission tutor for MSc in Electronic and Electrical Engineering
(2005 to 2011)
  • Assessed applications and answering queries.
  • Interviewed applicants to the MSc course to ensure that their English and technical abilities meet our course requirements. This is particularly important for students from China. Some of them have good technical abilities but weaker English communicating and listening skills. It is therefore crucial to interview these students prior to making decisions on their applications.
