The Tunisia gunman Seifeddine Rezgui was a top student just a month before he launched the deadly attack which killed 38.
Rezgui had "very good attendance" according to the university and sat his exams between 14th - 23rd May this year.
ITV News Middle East Correspondent Geraint Vincent reports:
An administrator at the university could not comment on what Rezgui did outside of classes, but said there are preachers in the mosques who are radicalizing young people.
Rezgui lived in the university town of Kairouan and shared a house with some of those arrested in connection with the attack.
Neighbours in the street say that they all disappeared a month ago.
