Students can register for the Leaving Cert written examinations in November from 9am on Monday.
While this year's Leaving Cert students received their calculated grades earlier this month, they will still have the option to sit their traditional written exams.
The State Examination Commission today said student can register to sit the exams through the Examinations.ie website.
Entries will be accepted over five days, closing at 5pm next Friday.
The written examinations start on Monday the 16th of November and end on Saturday 28th, subject to public health advice.
Results are expected to be issued in early February of next year 'at the earliest'.
In a statement, the SEC said: "Leaving Certificate candidates sitting the written examinations in November who opted to receive calculated grades will be credited with the higher subject grade achieved between the calculated grade and the written examination."
Oral and practical exams will not take place as part of the process.
However, coursework which had been completed in five subjects - such as home economics and PE - before schools closed will be included in the grades.
Almost 80% of students’ estimated grades given by their teachers and schools remained the same as part of calculated grading.
However, some schools, parents and students raised concerns that some of results had been 'downgraded' and that CAO points had risen as a result of slightly higher overall grades than usual.
