Personal tutor
Trinity College assigns a tutor to each undergraduate student. Tutors are academic staff members who look after the welfare and development of a student in relation to their academic progress. They can advise on such matters as choosing courses, assessments and exams and act as an advocate in dealing with the university. She/he will be a source of help and guidance throughout your time as a student. See the Senior Tutor website for further information.
Erasmus students have a co-ordinator whose function is similar to a tutor's.
