Almost 3,000 Leaving Cert grades will be upgraded today after students appealed the results.
Around 9,000 students submitted almost 17,000 grades to be re-checked by examiners, with the number of individual subject appeals jumping by 87.5% compared to 2018.
This year - the first since the introduction of a faster appeals process - 2,916 upgrades have been awarded.
The figure is almost double last year's number of 1,453.
According to the State Examinations Commission (SEC), the appeals process resulted in only two downgrades.
The SEC said it has been "very active" in alerting students about the revised appeals process - adding that viewing and appeal services were also more accessible.
In a statement, they said: "The earlier issue date for these appeal results means that third level applicants will now have full visibility on their options very early in the academic year rather than having to wait until mid-October as was the case previously.
"Candidates may opt to view their remarked examination scripts. If still unhappy, candidates can refer their appeal to a panel of Independent Appeal Scrutineers, who are fully independent of the staff and management of the SEC and the marking teams."
Results of the appeals will be available on the SEC's website from 10am.
The revised appeals process was introduced following a High Court case taken by student Rebecca Carter.
She claimed that the previous time-frame for Leaving Cert appeals meant that, in the event of a successful appeal, she would not have been able to start her course in time and would have had to accept a deferred offer for the following year.
In his judgement, Mr Justice Humphreys said the previous system was highly unfair to students and could not be repeated.
