2,820 students have applied to sit this year's postponed Leaving Certificate exams next month.
This represents just under 5% of the total number who had originally registered to sit the exams this year.
Registration closed this evening at 5pm.
While students received calculated grades, the exams themselves were postponed until November.
Anyone who had registered to sit the Leaving Cert prior to the announcement of calculated grades can sit the postponed tests.
The exams are scheduled to begin on Monday 16 November with Biology. During weekdays, one exam is being held each evening, beginning at 5.30pm.
The weekends are fuller, with two exams timetabled for each day. The first weekend sees English papers one and two scheduled for Saturday with both Maths papers on Sunday.
There are no oral or practical components to this year's exams and all unfinished coursework has also been excluded.
The State Examinations Commission said it would not be feasible or practical to assess these elements.
However, coursework in five subjects, which had been completed before schools closed, will form part of a student's assessment.
These subjects are Home Economics, Engineering, PE, Design and Communication Graphics, and the LCVP portfolio.
For all other subjects, grades will be awarded entirely on the outcome of the written paper.
The State Examinations Commission hopes to have results for students by early February.
Candidates who also received calculated grades will be credited with whichever subject grade is higher, between their Calculated Grade and the written examination.
Students who have applied for a college place via the CAO and who are entitled to an improved offer based on their results will receive that new offer in the form of a deferred place for the next academic year.
A student can sit exams in any or all subjects for which they had registered. There is no fee for registering to sit the exams, which will be held as usual in schools throughout the country.
Junior Certificate exams are also taking place for adult learners and early school leavers.
Students have until 5pm today to register via the online portal or, in the case of Leaving Certificate Applied students, via email.
