The majority of Leaving Certificate students have registered for the new calculated grades system as of Wednesday afternoon.
Some 48,075 students have signed up so far, and they have until 10pm on Thursday to apply.
More than 60,000 students are due to sit the Leaving Certificate, but it has been cancelled due to the pandemic.
Students can opt to sit the exam at a later date, but this has yet to be confirmed by the Government and it would not be in time for college admissions in September.
The calculated grades system will involve teachers assessing what grade they think a student would have received if they had sat the Leaving Cert examination.
