Over 120-thousand students will start their Leaving and Junior Cert exams this morning in 5,000 test centres across the country.
English is the first paper for everyone - those sitting the Applied Leaving have it combined with communications.
It's also the first time that a new course in Politics and Society will be tested in 41 pilot centres.
A record 37 per cent have registered to sit higher level Leaving Cert maths, up from about 20 per cent in 2011.
There is also a rise in the number of students who have applied to sit higher level exams in the Leaving Cert for many other subjects.
People have been reminiscing about their leaving cert experiences on twitter:
If you're doing the #LeavingCert keep in mind that I missed Guns N Roses at Slane in 1992 because according to my folks it was too close to my L.C. The bitterness has simmered within me ever since and I still cry myself to sleep at night. So, everything in perspective guys.

'Twas leaving cert eve
And all through the land
6th years said
They didn't give a damn
Grannies lit candles
But all we did was tweet
Cos sure lookit lads
Ye can always repeat #leavingcert
That's a H1 for me in the bag boys with them sweet rhymes x— Rhaínna (@rhxinna) June 5, 2018
