Members of the University and College Union (UCU) are continuing a marking and assessment boycott over pay and working conditions. The BBC spoke to students and staff at the University of Cambridge about how the situation is being handled there.
University students at 145 UK institutions are affected, as a dispute about staff pay and working conditions continues.
The action by the UCU covers all marking and assessments, as well as related work such as exam invigilation.
Following three days of strike action in November, the union had announced 18 days of industrial action during February and March, but called some off of those dates after making "significant progress across a range of issues".
The marking boycott began on 20 April and will carry on until employers make an improved offer, the UCU says.
