Students can start to apply for third level courses from today.
The Central Applications Office has opened for prospective students, and will remain open until the 1st of February.
A fee of €30 will be charged until the January 20 for registrations which will increase to €45 thereafter.
Past President of the Institute of Guidance Councillors, Betty McLaughlin, says students who are unsure should register now to get their CAO number.
She said: "If you're not sure about your course and very many are not, a good starting point is to say 'what am I good at, what subjects do I really enjoy, what excites me most and what am I passionate about?'"
