The deadline for students to apply for calculated grades in this year's Leaving Cert has been extended until midday.
Almost 60,000 had registered, but the Department of Education says it is conscious of some students being unable to sign-up.
Meanwhile The Minister for Education, Joe McHugh has said he would not accept a "half return" to school which would be required if the current two-metre social distancing guidelines remain in place in September.
The Donegal TD told RTÉ's Prime Time he cannot overrule public health advice, but he said the advice is changing and the Government would be informed by international advice.
He added he did not want to see children having to wear face masks in school.
Deputy McHugh added that while the current 2 meter rule will not facilitate the full return of students, he has not "given up" on children fully returning to school.
