Lecturer: Dr Sam Marsh

Module image

Continued disruption alert! Due to planned major downgrades to pensions of academic staff, members of the University and College Union have been striking at universities around the country. While the initial wave of strike action is over, the dispute has not been resolved, and there is likely to be more disruption after Easter, comparable to the first wave of strikes, unless a solution is found.

You can read more about the reasons for the dispute here, and you can also read an article I was asked to write for the Times Higher Education Supplement here.

This is the 2017-2018 course web page for MAS114: Numbers and Groups, Semester 2, which will be updated as the module progresses. For official course information, including timetabling and syllabus, please consult the list of current modules.
