There has been questions from UNIBEN prospective students on when the 2014/2015 clearance will commence.
Though there has not been any official date released by the school authorities, however, according to the 2013/2014 academic calendar the new session (2014/2015) is expected to commence on 10th January for new students and 17th January 2015 for old students.
I believe this will give you an idea concerning when the clearance will commence and also guide you towards your preparation for the clearance.
