You need to apply for pre-approval of the courses you plan to take at the host university. You must do this in order to make sure that the courses fulfill the course requirements in your curriculum, which is ultimately your own responsibility.
See deadlines and how to apply for pre-approval of courses.
Please remember to make sure that you have received a pre-approval of the courses you plan to take at the host university before departure. Remember to contact firstname.lastname@example.org if the approved courses are subjected to alterations.
In most cases you will have to apply for a pre-approval of courses, before you have been accepted to the courses at the host university.
If you are not accepted to the courses that ITU has pre-approved, you must apply for a new pre-approval.
You can do this even if the deadline has passed since this is an update of your first application.
