Let students examine (correct) other students deliveries

Examiner for other students

Examiners do not have access to any assignment groups where they have not been explicitly made an examiner. Therefore, it is perfectly safe to make a student an examiner on any assignment group.

Self-evaluation

You may also let students examine/correct their own deliveries. This may be useful if you require students to evaluate themselves. This will be far more useful when we implement a comment system.
