Two Dublin men have been fined €200 each for sitting each other's Leaving Certificate Physics exam four years ago.
Yale graduate Conor Dooney, 22, from Dun Laoghaire, who was described as a gifted student, sat Stephen Boucher's Higher Level Physics paper using his friend's student number.
Boucher, 22, from Foxrock, wanted extra points for a marketing degree, Dublin Circuit Criminal Court heard.
The two pleaded guilty to impersonating each other during the exam.
They were caught out after their Physics teacher heard rumours about what they had done.
