If your timetable shows a clash, please first make sure that the apparently conflicting classes occur in the same week.
The teaching timetable is planned and built to cater for the majority of students.
However, it is not possible to allow for every possibility. For example, the following are scenarios which are not planned for and so might lead to a clash:
Where a student is repeating a failed module
Where a student is taking modules in the wrong year in order to be able to change programme
