How to cheat in the Leaving Certificate

Infamous low-budget Irish movie from the '90s. One of the few films that everyone has heard of but few seen? It's about the break in to the Athlone building that holds the exam papers. Then the guy who got 7 A1s admits he cheated and the reaction is told in flashback. The acting is terrible (I didn't realise we had so many posh actors!) and the story is trite (everyone knows that the same questions keep coming up in the Leaving Cert exam anyway so why cheat?) but the film is still impressive because: It's in black and white; there are some famous cameos (Chris De Burgh as a garage attendant?); the pacing and editing are really well done; and some of the songs on the soundtrack are good. Strange that the director never followed up with another feature. Surely he didn't get blacklisted after this?
