A total of just 2,820 students are due to sit the postponed Leaving Cert today.
The exams will take place during evenings and weekends from today until December 11th.
Students who have already received calculated grades and decide to sit the written exams will be given the higher marks of the two.
Meanwhile, the number of Leaving Cert exemptions for Irish has increased by 16 percent in the past year.
It follows a change to the rules that a principal can sign off on the exemption instead of relying on a cert from a psychologist.
The Irish Independent reports the number of students getting the dispensation is now more than 6,000 compared with 5.076 in the 2018-19 academic year.
