If you make changes to your course selection during the semester, you must contact your academic advisor for new approval.
The School of Engineering cannot guarantee that students will manage to find replacements for all courses during the exchange studies. If you cannot find a course to replace all the courses you would have taken at home, you must recotake these later to get your degree at School of Engineering. The same applies if you fail a course at the partner university; you may have to take a replacement course at home. Re-exams can be very unusual abroad.
