The University Calendar is a useful resource as it not only shows staff and students the academic year but also includes things such as semesters, week numbers, if the university is in or out of semester and when the University is closed.
The Mathematics Learning Support Centre is open during the Autumn, Spring and Summer terms. These are shown in the representing colours, blue, yellow and green on the university calendar.
The Mathematics Learning Support Centre is not open out of semester (apart from the Special Assessment Period at the end of August) or when the University is closed.
