The term ‘supplementary resit’ can refer to a resit exam that replaces or combines different components of a module. For example, where a student has failed an exam and a coursework assignment, instead of retaking both components they may be required to sit one supplementary resit exam, covering all the required learning outcomes for that module, in order to progress/complete.
In some cases, the supplementary resit paper may differ from the exam resit paper, however some modules may have just one version of the resit paper which could be referred to as either exam resit or supplementary resit. You may see either terminology on your exam timetable.
