LET US TAKE YOU HIGHER INTERNATIONAL PROSPECTUS I chose to study Pharmacy at Queen’s because of its excellent reputation and high ranking status in the UK. I was attracted to study at the University by the impressive Lanyon Building campus – which has a great heritage and is a stunning landmark – and also by the low cost of living in Northern Ireland, which is much cheaper than the rest of the UK. I am having a lot of fun studying at Queen’s. The lecturers and tutors are very friendly and approachable. There are five other students from Asia in my class, and this mix of nationalities and local students provides an excellent opportunity to improve my English- speaking skills.
