If you would like an explanation of your grade, you can contact your lecturer or the examiner responsible for the assessment of your exam by phone or by e-mail. As long as you put forth your claim within a week after the announcement of the grade, you are entitled to receive an explanation. (With one exception: At oral examinations or assessments of practical skills, a request for an explanation must be made immediately on notification of the mark.)
The explanation may be given to you orally or in writing. We recommend that you ask for an explanation of your grade if you consider making an appeal against the grade.
