Lectures take place in each Department or Faculty, and form a key part of every course. In many cases they are compulsory and cover the key material which will form the basis of discussion and further work in supervisions.
In other subjects there is a wider choice of lecture courses, which should be selected with care, following discussion with your Director of Studies or supervisor; you should make time for any preparatory reading and attend consistently. Since a great deal of material is often covered in each lecture it is also important to allow time to read through your notes soon afterwards. They will later become a vital resource in your preparation for examinations.
The University provides a service offering personalised student timetables to the University’s Departments and Institutions - available here. Further details are often provided by Faculties and Departments, and Directors of studies can always offer advice.
Remember that members of the University are entitled to attend almost all lectures in any subject, so you are encouraged to make use of relevant interdisciplinary teaching and (as time allows) to explore your broader academic interests.
