Leaving Cert 2020 starts this evening with Biology.
Just over 2,500 students will be sitting the deferred papers.
Exams will continue for the next four weeks during evenings and weekends.
The exams traditionally kick off with English Paper One; however, this year students are beginning with biology.
Guidance counsellor Donnchadh O'Mahoney from Loreto College in Dublin said most are already taking college courses.
“The majority of students that are sitting these exams will have been offered college places this year and will have started college places,” he said.
“The reason they are going back to sit these exams is they probably want a college place further up on their CAO list that they really, really wanted.
“So they probably started these and they are studying in these but they said, ‘look I’ll take these exams and if I do better and get offered another one for next year brilliant – if I don’t, nothing lost, nothing gained.’”
