More than 120 thousand students begin their state exams this morning.
Nearly 57,000 Leaving Cert students face English Paper 1 this morning, while it's English and CSPE on the cards for the 62,000 Junior Cert students.
Education Minister Richard Bruton has wished the students luck, and had this advice: "People have to regard it as a marathon and not a sprint - it's over a long number of days and it's very important to stay fresh through that period."
He added: "You can often spend too much time regretting the answer you should have given in a paper that's gone where really people should take the opportunity to be cool going into their exams. Be very careful to read the questions that are asked so that you answer the actual questions that are asked."
Meanwhile, students are being reminded that these exams are not the "be all and end all".
The ISPCC also says that anyone who feels they can't cope with the stress of exams should call or text Childline.
The 24-hour phone line is available by phoning 1800 66 66 66 or by texting the word 'talk' to 50101.
Interim Chief Executive Caroline O'Sullivan says it's good to remember that there's help always available, if you feel you can't talk to family or friends.
