Education experts are warning that a new marking system could lead to more rechecks after the Leaving results come out next week.
Under the changes, students will have the potential to get eight different grades rather than the old 14.
They range from H1-H8 for Higher Level and O1- O2 for Ordinary Level papers.
Brian Mooney is a guidance counsellor that writes for the Irish Times, "the first and most important thing is that at both Higher and Ordinary level the banding is now every 10%", he said.
"So your A, Bs B1, B2 - all gone.
The most significant change is that in the past fails started at 40% on both Ordinary and Higher.
As of now you get no points and are deemed to have failed at Higher once you get to 30%."
