There's a documentary about broadcaster Stephen Byrne re-sitting his Leaving Cert, a Gogglebox special on TV3, and there's live coverage of the Mercury Music Prize . . .
Pick of the day
Leaving Again, 1015pm, RTÉ One
Nine years after broadcaster Stephen Byrne sat his Leaving Cert, he decided to sit the series of exams all over again.
In this personal and honest documentary, the now 27-year-old returns to school to attempt the same seven subjects he studied the first time around. He describes his 2009 Leaving Cert year as one of the worst years of his life.
He had moved school, was coming to terms with his sexuality and had just started working in RTÉ. Mix that with a normal helping of teenage angst and you’ve got a recipe for Leaving Cert disaster.
In September 2017, Stephen Byrne decided to go back to do the Leaving Cert, to find out if he would fare better second time around at a more mature age.
