Courses under another programme or at another university
You may apply for pre-approval to take an elective under another programme at SDU or at another university. However, you may only do so if the courses in question are relevant to your programme and are offered at the time for electives indicated by your programme's process model.
Some courses under other programmes may already have been pre-approved by your Study Board as electives available to you. In that case, you'll find the courses in the syllabus.
